High Pressure 500 Pilot Operated Chek

The High Pressure 500 Pilot Operated Chek is the latest addition to Lee’s line of miniature check valves. This valve acts like a normal check valve until pressure is applied to the pilot port, which then allows flow in the direction that would normally be blocked.
