Wholesale PricingThe Range Guard 1-1/2-inch Mechanical Gas Shut-Off Valve (P/N 120074, full part number 60-120074-001) automatically cuts the gas supply to protected cooking appliances the moment a Range Guard or Industry Guard kitchen fire suppression system actuates. This is a mechanical valve operated by cable tension. During standby, the valve is held open by tension on a 1/16-inch Badger cable running through the detection network back to the release mechanism. When the system actuates, cable tension releases and an internal spring closes the valve, stopping gas flow to the protected appliances.
The 1-1/2-inch size is suited to larger commercial kitchen installations with higher combined fuel demand, such as banks of heavy-duty fryers, large griddles, multiple cooking appliances served by a single shared supply line, or any configuration where the gas piping at the point of installation is a 1-1/2-inch line. As with all sizes in this mechanical valve family, no electrical power or signal is required for the valve to close, making it fully integrated into the Range Guard system's mechanical actuation cable network and independent of building electrical systems.

Kitchen suppression systems are pre-engineered systems under NFPA 17A and NFPA 96. Gas valve installation must be performed by a certified Range Guard distributor, in coordination with a licensed gas fitter for the physical pipe connections.
- Confirm Pipe Size: The valve must match the pipe size at the point of installation as specified in the system's design documentation. The 1-1/2-inch size is appropriate only where 1-1/2-inch gas piping is used at the installation point.
- Cable Tension: Proper cable tension is critical for reliable valve operation. A certified technician sets and verifies cable tension during installation and at each semiannual service visit.
- Semiannual Professional Service: A qualified technician tests the valve by manually actuating the system and confirming the valve closes completely and resets correctly.
- Post-Discharge Reset: After any system actuation, the valve must be inspected and reset by a qualified technician before gas service is restored.
Can I use two smaller valves instead of one 1-1/2-inch valve to serve multiple appliances?
That depends on your system's gas piping layout and design. In some configurations, individual valves at each appliance's supply line are specified rather than a single valve on a shared main line. Your certified Range Guard distributor determines the correct valve placement based on the piping design and which appliances need to be shut off on system actuation.
Does this valve need electrical power to operate?
No. This is a fully mechanical valve that operates on cable tension release alone. No electrical power, no solenoid, and no control panel signal is required for it to close when the system actuates.
What other sizes are available?
Range Guard mechanical gas shut-off valves are available in 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, and 3-inch sizes to cover the full range of commercial kitchen gas piping configurations.
