BGA158 Series automatic gas valves are electrically operated shut-off valves that are normally in the closed position and open on an electrical demand signal from a thermostat or other controlling device. The BGA158 can be operated with natural gas or LP at pressures up to 0.5 psi. Typical applications are agricultural heating equipment, commercial cooking equipment, wall furnaces or other heating equipment. Their compact size permits installation in space-restrictive applications.
