Robertshaw 700-503 Gas Valve

The Robertshaw 700-503 Gas Valve is a millivolt combination gas control designed for heavy-duty HVACR applications, including high-capacity 1" pipe systems up to 720,000 BTU. This wall thermostat actuated valve features a 1/2" FPT inlet and a 3/4" FPT straight-thru outlet, with additional 1/2" FPT side taps provided for installation flexibility in tight furnace or pool heater cabinets. As a non-regulated (7000BMV) model, it is engineered for systems where external pressure regulation is already present. The 700-503 is rated for 250mV to 750mV operation and is fully compatible with thermopile-driven standing pilot systems. It includes NEMA standard terminals with a 1/4" and 3/16" quick-connect block to prevent mis-wiring during field replacement. The multiposition mounting capability allows for orientation in any direction except upside down, ensuring reliable performance across a variety of commercial cooking and heating equipment setups.

• Versatile Application: Suitable for furnaces, commercial water heaters, and pool heaters with a capacity of up to 240,000 BTU for this specific configuration.
• Enhanced Connectivity: Features a combination of screw/spade terminals and 1/4" pilot tubing outlets for secure electrical and gas connections.
• Industrial Durability: Rated for ambient temperatures from -40°F to 175°F with an inlet filtered screen to protect internal components from debris.
