White-rodgers 07 64 742S1 Gas Pilot Safety Valve

Product Description

The WHITE-RODGERS 07 64 742S1 is a thermocouple-operated gas pilot safety valve designed for residential and light commercial heating systems. It operates on a coil voltage of 20 to 30 millivolts (mV), drawing power directly from the thermocouple circuit — no external power source required. The valve controls gas flow to the pilot assembly and shuts off gas automatically if the pilot flame is lost, providing a critical safety function. It accepts 1/2-inch inlet and 1/2-inch outlet pipe connections and is rated for all domestic heating gases, including natural gas and propane. Licensed HVAC technicians and gas heating service professionals are the typical installers of this component.

This pilot safety valve is suited for use in residential gas furnaces, boilers, space heaters, and other domestic gas-fired heating appliances that rely on a standing pilot ignition system. It features an inlet pressure tap, allowing technicians to verify incoming gas pressure during commissioning or troubleshooting without removing the valve from the line. The 1/2-inch by 1/2-inch pipe sizing makes it a common fit across a wide range of standing-pilot heating equipment.

• Inlet pressure tap included for field pressure verification
• 1/2-inch inlet by 1/2-inch outlet pipe connections
• Compatible with all domestic heating gases including natural gas and LP
• Compact design suitable for standing-pilot gas appliances

Compatibility

Designed as an OEM-style replacement safety valve for residential and light commercial gas-fired heating appliances equipped with standing pilot ignition systems and thermocouple-based safety circuits.

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas service professional in accordance with the appliance manufacturer instructions and applicable local gas codes. Shut off the gas supply at the service valve and allow the system to depressurize fully before removing or installing this valve. Use approved pipe thread sealant on all connections and verify for leaks with a listed leak-detection solution before returning the appliance to service. Confirm thermocouple output voltage is within the 20 to 30 mV operating range before replacing the valve to rule out a failed thermocouple as the root cause.
