When you're servicing compact heating systems in recreational vehicles, the Robertshaw 710-203 Gas Valve is a specialized low-capacity hydraulic snap-action valve built for precision in tight footprints. This 710 Series gas valve features a non-regulated design with a 36-inch capillary, making it a direct fit for RV furnaces and appliances requiring 1/2" NPT connections. It supports multiple fuel types, including natural gas and LP gas, delivering a capacity of 70,000 BTU for NG and 112,000 BTU for LP. Designed for versatility, it includes two 1/2" x 3/8" NPT reducer bushings and a 1/4" tubing pilot outlet. The three-position gas cock (Off-Pilot-On) and standard NEMA terminals ensure a straightforward swap-out during field service. With an ambient temperature rating up to 175°F and a filtered inlet screen, this valve maintains reliable gas flow control in demanding mobile environments.
