Maxon Combustion Normally Closed Gas Shutoff Valve Hydramotor Actuator, 4" Flange, 510 Cv (120V)

MAXON electro-mechanical valves are electrically actuated fuel shut-off valves. The valves are designed for a fast acting return to the at rest position upon removal of a control voltage signal. Motorized automatic and manual actuators are available depending on application needs. In addition, normally-closed and normally-open options are available. The normally-closed versions will shut off flow when de-energized and pass flow when energized. The normally-open versions will shut off flow when energized and pass flow when de-energized. Electro-mechanical valves are also offered in configurations that meet hazardous locations.
