Wholesale PricingThe Range Guard 3/4-inch Mechanical Gas Shut-Off Valve (P/N 120071, full part number 60-120071-001) 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, not by an electrical signal. During standby, the valve is held open by tension on a 1/16-inch Badger cable running from the valve through the detection network back to the release mechanism. When the system actuates, cable tension relaxes and an internal spring closes the valve, stopping gas flow to the protected appliance instantly.
Cutting fuel supply simultaneously with agent discharge is a critical part of the suppression strategy for gas-fueled appliances. Continuing to supply gas to a burner during and after a wet chemical discharge can reignite the fire after the agent has knocked down the initial flame. The mechanical valve ensures this shutoff happens at the same moment as system actuation, with no dependency on a separate electrical signal. The 3/4-inch size serves smaller commercial kitchen appliances on 3/4-inch gas supply lines, such as smaller fryers, range tops, and similar equipment with lower fuel demand.

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 serving the protected appliance. Confirm pipe size with your system's design documentation before ordering.
- Cable Tension: Proper cable tension is critical for reliable 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.
How does a mechanical gas valve differ from an electric gas valve?
A mechanical gas valve closes when cable tension releases during system actuation, requiring no electrical power or signal to operate. An electric gas valve closes in response to a solenoid activation signal. Range Guard systems use mechanical gas valves as standard, making the gas shutoff fully independent of electrical power and integrated directly into the mechanical actuation cable network.
What if I need a larger valve size?
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. Select the size that matches the pipe serving the protected appliance as specified in your system design.
Does the cable block come with the valve?
Yes. A cable block is included with the valve and is used to connect the Badger cable to the valve's control stem. The 1/16-inch Badger cable itself is a separate component ordered through your certified Range Guard distributor.
