High Pressure 375 Pilot Operated Check Valve

The Lee Company’s new High Pressure 375 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 5,000 psi. The maximum restriction when piloted open is only 110 Lohms.


The High Pressure 375 Pilot Operated Chek is available in forward and reverse free flow configurations, and the metal components are constructed entirely of stainless steel for durability and long life. Nominal weight is just 20 grams. Each Chek is 100% tested and inspected to ensure reliable, consistent performance.
