This can be relevant in retrofit installations where replacing the entire gas valve is impractical but adapting it to work with the ANSUL system is feasible.\u003c\/p\u003e\n \u003cp\u003eThe non-UL status of the 426890 is an important consideration for code compliance. Most AHJs require UL-listed components throughout a fire suppression system. If a UL-listed gas valve replacement is required, the appropriate ANSUL UL-listed mechanical gas shutoff valve series (055598 through 055610) should be used instead. The 426890 should only be specified by a licensed ANSUL fire suppression contractor who has confirmed its acceptability for the specific installation.

Engineered for environments where a 2-inch supply is mandatory, such as industrial baking ovens and massive food processing lines, this valve provides the highest flow coefficient (Cv) in the Range Guard lineup. It ensures that even during peak production hours, your high-BTU equipment receives a steady fuel supply without the pressure fluctuations that cause appliance starvation.\u003c\/p\u003e\n \u003cp\u003eOperating on a principle of passive reliability, the 120075 is a purely mechanical fail-safe.

055601 Mechanical Gas Valve is a mission-critical component within the Ansul R-102 and Piranha Restaurant Fire Suppression Systems. Designed for 1-inch NPT piping, this valve serves as the primary mechanical safety interlock for commercial kitchens. Its sole purpose is to provide an instantaneous, fail-safe termination of natural gas or liquid propane (LP) flow the moment a fire is detected under the kitchen hood.\u003c\/p\u003e\n \n \u003cp\u003eIn the high-stakes environment of a professional kitchen, a fire is often fueled by the continuous flow of gas to the burners. Even if the fire suppression agent (ANSULEX) is discharged onto the flames, the fire can re-ignite if the gas line remains open. The Ansul 055601 ensures that the \"fuel\" side of the fire triangle is removed simultaneously with the application of the extinguishing agent. By choosing the 1-inch model, you are selecting the industry-standard size for mid-sized cooking lines, providing the perfect balance of gas volume and rapid shut-off response.\u003c\/p\u003e\n\n \u003ch3\u003eThe Engineering of Mechanical Reliability\u003c\/h3\u003e\n \u003cp\u003eOne of the most frequent questions from facility managers is: \"Why use a mechanical valve instead of an electric solenoid valve?\" The answer lies in the \"Fail-Safe\" engineering of the Ansul 055601.\u003c\/p\u003e\n\n \u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eIndependent of Power:\u003c\/strong\u003e Unlike electric valves, the 055601 does not require a building's electrical system to function.

055607 Mechanical Gas Valve (1-1\/2\") is a mission-critical safety component designed to integrate seamlessly with ANSUL R-102 and PIRANHA fire suppression systems. In a commercial kitchen fire, the extinguishing agent (ANSULEX) is only half of the solution; the other half is the immediate isolation of the fuel source. The 055607 valve provides an automatic, mechanical fail-safe that snaps shut the moment the fire system is triggered, preventing the gas line from feeding a fire and significantly reducing the risk of a catastrophic re-flash.\u003c\/p\u003e\n \n \u003cp\u003eEngineered for high-volume gas lines, the 1-1\/2\" NPT 055607 model is typically installed on the main supply line serving multiple appliances, such as heavy-duty ranges, charbroilers, and large deep-fryer batteries. Because it is a purely mechanical device, it does not rely on electrical power or solenoids to function, ensuring it remains operational even during a total building power failure.

During a system discharge, the 055610 automatically cuts off the gas supply to all protected cooking appliances — preventing reignition of cooking oil or grease fires after the wet chemical agent has suppressed the initial fire event. The 2-inch pipe size makes the 055610 the largest in the ANSUL mechanical gas valve series, suited for high-volume commercial kitchen installations with the largest gas supply mains.\u003c\/p\u003e\n \u003cp\u003eThe complete ANSUL mechanical gas valve series covers five pipe sizes for the full range of commercial kitchen gas supply configurations. The 055610 (2-inch) is the largest, with the series also including the 055598 (3\/4-inch), 055601 (1-inch), 055604 (1-1\/4-inch), and 055607 (1-1\/2-inch). All models are UL listed and designed specifically for ANSUL R-102 and Piranha system integration — ensuring reliable, coordinated gas shutoff with the ANSUL Automan control head or compatible release module.

The 12792 uses the same latch-and-spring pull-to-close mechanism as the 12790 (3\/4-inch) and 12791 (1-inch) — a trip cable from the Amerex MRM or PRM release module pulls the latch on system activation, allowing an internal spring to close the valve and cut off the gas supply to the protected cooking appliances. The 1-1\/4-inch pipe size makes the 12792 the correct gas valve for larger commercial kitchen gas supply configurations where multiple high-BTU appliances share a 1-1\/4-inch main supply line.\u003c\/p\u003e\n \u003cp\u003eIn large commercial kitchens — busy restaurants, school cafeterias, hospital kitchens, and institutional food service operations — the gas supply manifold serving the cooking line is often 1-1\/4-inch or larger to handle the combined BTU demand of multiple fryers, ranges, and griddles operating simultaneously. The 12792 provides the commercial kitchen emergency gas shut off valve capability needed for these larger configurations, cutting off the full 1-1\/4-inch gas supply during a Amerex KP system discharge.

All three are available through authorized amerex distributors as standard amerex fire suppression system parts. For fire protection contractors managing large commercial kitchen portfolios, stocking all three sizes ensures the correct 1 inch gas valve, 3\/4 gas valve, or 1 1\/4 gas valve is immediately available for any Amerex KP installation or replacement situation without waiting for special orders.\u003c\/p\u003e\n \u003c\/div\u003e\u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"accordion-item\"\u003e\n \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n \u003ctable class=\"specs-table\"\u003e\n \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n \u003ctbody\u003e\n \u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eAmerex Corporation\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e12792\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePipe Size\u003c\/td\u003e\n\u003ctd\u003e1-1\/4 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eMechanism\u003c\/td\u003e\n\u003ctd\u003ePull-to-close mechanical latch with spring closure\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCompatible Systems\u003c\/td\u003e\n\u003ctd\u003eAmerex KP kitchen fire suppression\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eGas Type\u003c\/td\u003e\n\u003ctd\u003eNatural gas and LP gas (UL listed)\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eUL Listed, NFPA 96, OEM Original\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003c\/tbody\u003e\n \u003c\/table\u003e\n \u003c\/div\u003e\u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"accordion-item\"\u003e\n \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Compliance (NFPA 96)\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n \u003cp\u003eInstall the 12792 in the 1-1\/4-inch gas supply line upstream of all protected cooking appliances per NFPA 96, the amerex kp system manual, and local gas code.

Under normal operation, the valve is held open by a latch mechanism. When the system activates, a trip cable from the Amerex MRM or PRM release module pulls the latch, allowing an internal spring to close the valve and shut off the gas supply safely and automatically — preventing fuel from reaching the protected cooking appliances during and after the wet chemical suppression discharge.\u003c\/p\u003e\n \u003cp\u003eThe 3\/4-inch pipe size of the 12790 is the smallest in the Amerex mechanical gas valve series, making it the correct gas shut off valve for range applications where the gas supply line to a single small cooking appliance — a countertop fryer, small range, or standalone griddle — runs through 3\/4-inch pipe. Selecting the correct valve size for the actual pipe size is essential: an undersized valve creates gas flow restriction that affects appliance performance, while an oversized valve may not fully seal under the lower pressure conditions of a small-appliance gas line.\u003c\/p\u003e\n \u003cp\u003eThe 12790 is UL listed for both natural gas and LP gas service.

It uses a pull-to-close latch mechanism — under normal operation the valve is held open by a latch, and when the suppression system activates, a trip cable from the release module pulls the latch to close the valve via an internal spring, shutting off the gas supply automatically and safely. This gas shut off valve for range applications is UL listed for both natural gas and LP gas service, covering the two fuel types found in commercial kitchen installations.\u003c\/p\u003e\n \u003cp\u003eThe Amerex 12791 is the 1-inch companion to the 12790 (3\/4-inch) and 12792 (1-1\/4-inch) mechanical gas valves — together covering the three most common gas supply line sizes for commercial kitchen cooking equipment. Per NFPA 96, an automatic gas shutoff valve is required for all gas-fueled appliances protected by a kitchen fire suppression system. The mechanical pull-to-close design of the 12791 requires no electrical power to actuate — the spring closure mechanism operates entirely via the mechanical cable from the KP system's MRM or PRM release module, making it inherently fail-safe during power outages.\u003c\/p\u003e\n \u003cp\u003eFor fire protection contractors completing Amerex KP system installations, keeping all three gas valve sizes (12790, 12791, and 12792) in inventory as part of your amerex fire suppression system parts supply ensures the correct gas range shut off valve is available for any commercial kitchen gas line size encountered. The gas safety shut off valve must be tested at every semi-annual NFPA 17A and NFPA 96 inspection — triggering a simulated system discharge and confirming the valve closes fully and the manual reset functions correctly.

As the largest standard unit in the GV series, it serves as the primary fuel interruptor for main gas headers. By immediately terminating the fuel supply to large-scale appliance lines upon system discharge, the GV-200 provides critical source isolation, effectively starving the fire of thermal energy and preventing catastrophic re-ignition.\u003c\/p\u003e\n \u003cp\u003eOptimized for industrial food processing and high-volume commercial kitchens, the GV-200 features a spring-loaded fail-closed design.

The 1-1\/2-inch pipe size of the GV-150 is typical in high-volume commercial cooking operations — large restaurant chains, cafeteria kitchens, and institutional food service facilities where multiple high-BTU cooking appliances share a larger-capacity gas supply manifold. During system discharge, the GV-150 automatically closes the gas supply valve for range and manifold configurations, eliminating the fuel source and preventing reignition per NFPA 96 requirements.\u003c\/p\u003e\n \u003cp\u003eAs the second-largest model in the Pyro-Chem GV series (with the GV-200 for 2-inch pipe being the largest), the GV-150 is specified for the highest-capacity single-zone Kitchen Knight II installations. The gas shut off valve for range applications at this pipe size requires reliable, full-port closure under the higher gas volumes present in 1-1\/2-inch supply lines — and the GV-150's factory-listed design ensures that performance consistently. The gas safety shut off valve function of the GV-150 is critical in large commercial kitchens where a system discharge must simultaneously shut off gas to multiple high-BTU appliances.\u003c\/p\u003e\n \u003cp\u003eThe complete Pyro-Chem GV series — GV-75 (550593) through GV-200 (551049) — is available through authorized pyro chem distributors with full pyro chem price list pricing.

The GV-125 automatically closes the gas supply line during a system discharge, preventing reignition of protected cooking equipment after the wet chemical agent has suppressed the initial grease fire. As a gas safety shut off valve, the GV-125 is required by NFPA 96 for all commercial kitchen fire suppression systems protecting gas-fueled appliances where the supply pipe is 1-1\/4-inch.\u003c\/p\u003e\n \u003cp\u003eThe 1-1\/4-inch pipe size of the GV-125 makes it the correct gas range shut off valve for medium-capacity commercial kitchen gas supply configurations — typically serving larger fryers, ranges, or multi-appliance manifolds where gas flow demand exceeds what a 1-inch line can support. Selecting the correct GV model for the pipe size is critical: an undersized gas valve creates a restriction that reduces appliance performance during normal operation, while an oversized valve may not properly seal under low-pressure conditions. Always match the commercial kitchen gas shut off valve to the actual pipe size using the pyro chem kitchen knight manual specifications.\u003c\/p\u003e\n \u003cp\u003eThe GV-125 is part of the complete Pyro-Chem GV series spanning 3\/4-inch through 2-inch pipe sizes, all available through authorized pyro chem distributors. The pyro chem price list and pyro chem supply channels provide complete ordering information for the entire GV series. The gas shut off valve for range and commercial kitchen emergency gas shut off valve applications covered by the GV series make it one of the highest-specification components in any Pyro-Chem kitchen fire suppression system installation.\u003c\/p\u003e\n \u003c\/div\u003e\u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"accordion-item\"\u003e\n \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n \u003ctable class=\"specs-table\"\u003e\n \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n \u003ctbody\u003e\n \u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003ePyro-Chem (A Johnson Controls Brand)\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e550595\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eGV-125\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003ePipe Size\u003c\/td\u003e\n\u003ctd\u003e1-1\/4 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eAutomatic gas shutoff during system discharge\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCompatible Systems\u003c\/td\u003e\n\u003ctd\u003ePyro-Chem Kitchen Knight II\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eUL Listed, NFPA 96 compliant, OEM Original\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003c\/tbody\u003e\n \u003c\/table\u003e\n \u003c\/div\u003e\u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cdiv class=\"accordion-item\"\u003e\n \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Compliance (NFPA 96)\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n \u003cp\u003eInstall the GV-125 in the 1-1\/4-inch gas supply line upstream of the protected cooking appliances per NFPA 96 and local gas code requirements.

In the high-stakes environment of a professional kitchen, fire suppression is a multi-stage process. While the wet chemical agent works to knockdown flames, the GV-75 performs the equally critical task of Fuel Source Interruption. By automatically severing the gas supply the moment a discharge is triggered, the GV-75 ensures that ranges, fryers, and broilers cannot continue to feed thermal energy into the hazard zone.\u003c\/p\u003e\n \n \u003cp\u003eConstructed for industrial reliability and designed for seamless mechanical interfacing, the GV-75 is the industry standard for 3\/4-inch gas lines.

Engineered with normally closed (NC) safety logic, the EGVSO-75 physically blocks the flow of natural gas or liquid propane unless the system is actively powered and monitored. In the event of a fire trip, a building power failure, or a manual emergency stop, the valve snaps shut instantly, starving the cooking battery of fuel before a localized flare-up can escalate.\u003c\/p\u003e\n \u003cp\u003eUnlike traditional mechanical valves that rely on cable-and-pulley systems, the EGVSO-75 uses an electromagnetic interlock to achieve instantaneous shutdown. When power is cut -- whether intentionally or by fault -- the internal compression spring returns the valve plunger to its closed seat without any human intervention. This fail-to-safe default is the defining characteristic of modern solenoid gas valve design.\u003c\/p\u003e\n\n \u003ch3\u003eConduit-Based Routing Advantage\u003c\/h3\u003e\n \u003cp\u003eIn many modern kitchen architectures -- high-rise hotels, stadiums, and historical renovations -- routing mechanical cable from a control head to the gas line is physically impossible or cost-prohibitive. The EGVSO-75 replaces that cable run with standard electrical interlock wiring, allowing installers to navigate tight corners and floor-to-ceiling offsets with ease and eliminating cable-bind issues associated with corner pulleys.\u003c\/p\u003e\n\n \u003ch3\u003eScalable Multi-Zone Isolation\u003c\/h3\u003e\n \u003cp\u003eA single fire system can be wired to multiple EGVSO-75 valves, enabling the simultaneous shut-off of separate gas manifolds across a large facility. This level of automated fuel control is not achievable with mechanical valves.
