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. It is held open by a stainless steel cable connected to the system control head; upon activation, the tension is released and a heavy-duty internal spring slams the valve disc into the seat. This purely mechanical operation avoids the power-failure trap, ensuring functionality during total building power outages. Its high flow coefficient (Cv) minimizes pressure drop, ensuring that industrial-scale charbroilers and fryer batteries receive consistent gas volume without performance fluctuations.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 2: Technical Specifications --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ctable class=\"specs-table\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eFeature\u003c\/th\u003e\n              \u003cth\u003eDetails\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \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\u003e551049 (Model GV-200)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePipe Diameter\u003c\/td\u003e\n              \u003ctd\u003e2-inch NPT\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eValve Type\u003c\/td\u003e\n              \u003ctd\u003eMechanical \/ Spring-Loaded\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eHousing Material\u003c\/td\u003e\n              \u003ctd\u003eCorrosion-Resistant Bronze \/ Cast Iron\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePressure Rating\u003c\/td\u003e\n              \u003ctd\u003e5.0 PSI (Standard Gas Service)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eSystem Interface\u003c\/td\u003e\n              \u003ctd\u003eMechanical Cable Actuation\u003c\/td\u003e\n            \u003c\/tr\u003e\n          \u003c\/tbody\u003e\n        \u003c\/table\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Installation \u0026 Safety --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Safety\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003cp\u003eThe GV-200 must be installed by a licensed fire suppression technician in accordance with the Kitchen Knight II or Monarch design manual and applicable local gas codes. Due to its robust 2-inch casting, the valve is significantly heavier than smaller GV-series units. The 2-inch NPT piping must be securely supported with heavy-duty hangers on both sides of the valve to prevent mechanical stress on the manifold connections during the high-torque trip sequence.\u003c\/p\u003e\n        \u003cp\u003eThe mechanical actuation cable must be routed without kinks or sharp bends, and cable tension must be set to factory specifications to ensure the spring holds the valve fully open during normal operation. After installation, the technician must verify full valve travel by performing a manual trip test and confirming positive gas shutoff before the system is placed in service. Once tripped, the GV-200 requires a manual reset by a certified professional, serving as a secondary safety protocol to prevent unburned gas from being re-introduced into the hazard zone before a full fire audit and inspection have been completed.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 4: FAQ --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eFAQ\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ch3\u003eWhat is the strategic benefit of a 2-inch valve over multiple smaller valves?\u003c\/h3\u003e\n        \u003cp\u003eUtilizing a single GV-200 on the main gas header simplifies the manifold architecture and reduces the number of potential failure points.

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.

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.

In large-scale culinary and industrial environments, the GV-300 serves as the definitive mainline gas sentinel. While discharge nozzles handle flame knockdown, the GV-300 performs the equally vital task of fuel supply isolation. This 3-inch NPT Normally Open (NO) valve automatically terminates the fuel supply to an entire battery of gas-fired appliances the moment the fire system is actuated.\u003c\/p\u003e\n        \u003cp\u003eUnlike electrical solenoid valves that are susceptible to power surges or localized electrical failures during a fire, the 550186 operates on an immutable mechanical principle. It is the definitive fail-safe for UL 300 and NFPA 96 compliance, ensuring that a fire is starved of its energy source before it can re-ignite or migrate into the exhaust plenum. For contractors and facility directors, the GV-300 represents the pinnacle of industrial-grade gas security, providing a ruggedized, power-independent solution for high-volume mainline manifolds.\u003c\/p\u003e\n\n        \u003ch3\u003eTension-Release Actuation Logic\u003c\/h3\u003e\n        \u003cp\u003eThe GV-300 is integrated into the detection network via a 1\/16\" stainless steel cable. During the ready state, the Pyro-Chem Control Head maintains constant detection line tension, holding the valve's internal gate in the open position. The moment a thermal fusible link melts or a manual pull station is triggered, the control head releases this tension.\u003c\/p\u003e\n\n        \u003ch3\u003eSpring-Loaded Kinetic Closure\u003c\/h3\u003e\n        \u003cp\u003eOnce the cable tension is removed, a heavy-duty internal compression spring instantly expands, snapping the valve's internal plug into the seated position within milliseconds. This ensures gas flow is stopped almost simultaneously with the discharge of the suppression agent, preventing the fuel-feeding of an active kitchen fire.\u003c\/p\u003e\n\n        \u003ch3\u003eManual Reset Safety Protocol\u003c\/h3\u003e\n        \u003cp\u003eOnce the valve has tripped, it cannot be reopened by simply re-tensioning the cable. A technician must physically reset the valve at the body, ensuring a professional has inspected the line for leaks or damage before fuel is reintroduced to the facility.\u003c\/p\u003e\n\n        \u003ch3\u003eHigh-Flow 3-Inch Bore Design\u003c\/h3\u003e\n        \u003cp\u003eThe internal porting of the 3-inch NPT valve is machined to maximize flow with minimal pressure drop, keeping the pressure loss well within the tolerances required by NFPA 54 fuel gas code for high-BTU culinary batteries.
