Lee Company’s new 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. This new valve is ideal for high pressure hydraulic applications with system pressures up to 5000 psi. The maximum restriction when piloted open is only 60 Lohms.
