ASCO's Modular Fuel Gas Shut-Off Valves combines the 8214(200) solenoid valve with the V710(B) & AH(E) electro-hydraulic motorized valves, making them suitable for heating equipment, furnaces, boilers, kilns, ovens, and gas generators in industrial applications. They offer on-off control of fuel gas, as well as a proof of closure, optional visual indication, and silicon-free constructions.
