Robertshaw 700-400 Gas Valve
The Robertshaw 700-400 is an industry-standard 24V combination gas valve designed for versatility in residential and commercial heating applications. This uni-couple unit features a 1/2" NPT inlet and a 3/4" NPT outlet, and is factory-set for natural gas (NG) but includes a LP conversion kit for propane field setups. As an exact replacement for EF680006, this high-capacity valve is rated up to 100,000 BTU, making it a reliable solution for various furnace and boiler configurations. The low-profile design and multiposition mounting capability allow for easier installation in tight cabinets. Technicians value the 700 series for its manual pilot gas filtration and the inclusion of a pilot adjustment screw to ensure stable thermocouple output. Whether you are performing a Robertshaw gas valve replacement or upgrading a intermittent pilot ignition system, the 700-400 offers consistent 3.5" WC manifold pressure and high-flow performance across a wide operating temperature range.
- Universal Compatibility: Directly replaces model EF680006 and works with both 1/2" and 3/4" piping configurations.
- Field Convertibility: Includes necessary components for Natural Gas to LP conversion to suit job site requirements.
- Compact Form Factor: Reduced dimensions facilitate installation in space-constrained equipment housings.
- Reliable Regulation: Precise gas pressure regulator maintains steady flow for optimal combustion efficiency.
The valve features standard 1/4" spade terminals for 24V AC thermostat control connections. Ensure the transformer has sufficient VA capacity to handle the solenoid coil draw during the heating cycle.
Is the 700-400 gas valve compatible with standing pilot systems?Yes, this is a standing pilot valve that utilizes a millivolt thermocouple to verify the pilot flame before allowing main burner gas flow via the 24V operator.
Can this valve be mounted in any orientation?Professional installation allows for mounting in any position except upside down to prevent debris from fouling the internal valve seat.
