11LV44 – 1/4″ – arctic service

The 11LV44 is a two position, three-way normally closed block and bleed Manual Reset Relay valve. It is designed to establish Supply-to-Valve output pressure with manual Pull positioning of the Knob. Once the Black Knob is pulled outward and Pilot Supply pressure is applied, the Relay’s normal in-service placement will be maintained. A loss of Pilot Supply pressure will block the Supply (inlet) port and exhaust the accumulated pressure within the receiving control circuit.
