11RRS87 – 1/4″ – panel mount

The 11RRS87 is a two position, three-way panel mount, normally closed block and bleed, Pilot supply pressure actuated valve. It is designed to establish Supply-to-Valve output pressure with manual Pull of the handle. Once the valve handle is pulled 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 operating pressure within the receiving control circuit. To close the valve, Push on the valve handle to release downstream pressure.
