Robertshaw 700-402 Gas Valve

The Robertshaw 700-402 Gas Valve is a 24V combination control designed for high-capacity applications up to 240,000 BTU. This 1/2 inch x 3/4 inch NPT valve is a standard in the field for its multi-position mounting capability, allowing installers to orient the unit in any direction except upside down. As a Uni-Kit model, it is factory-configured for natural gas with a 3.5 inch WC regulator setting but includes a conversion kit for LP gas (liquid propane) applications. This 700 Series valve features 1/2 inch side outlets and a 1/4 inch pilot outlet, providing the versatile terminal connections (screw or spade) required for rapid field replacements. Engineered for reliability in temperatures ranging from -40°F to 175°F, this valve handles a maximum inlet pressure of 14 inches WC (0.5 PSI). Technicians will appreciate the filtered inlet screen and the integrated gas cock dial with clear Off-Pilot-On markings for straightforward troubleshooting and maintenance.

• Universal Compatibility: Includes reducer bushings and a conversion kit to replace multiple OEM gas valves in the field.
• High BTU Capacity: Rated for systems up to 240,000 BTU, making it suitable for both residential and light commercial furnaces or boilers.
• Flexible Installation: The multi-position design and compact swing radius fit into tight cabinet spaces where other controls fail.
• Robust Construction: Features NEMA terminals and a pilot gas filter to protect internal components from debris in the gas line.
• Reliable Regulation: Maintains consistent manifold pressure for optimal combustion efficiency across various gas types.

Can this valve be adjusted for higher altitudes?
Yes, the pressure regulator can be field-adjusted using a manometer to meet the specific manifold pressure requirements dictated by the appliance manufacturer and local elevation.

Is the pilot safety magnet replaceable?
The 700-402 features an integrated automatic pilot safety valve; if the internal magnet fails to hold, the primary operator or the entire valve assembly should be inspected for proper millivolt output from the thermocouple.

Will this work with intermittent pilot ignition (IPI) systems?
This specific model is designed as a standing pilot combination valve. For electronic spark or hot surface ignition systems, verify that the control module is compatible with a 24V AC, 0.2 Amp draw.
