The Lee Company's new High Pressure 375 Pilot Operated Chek^® is a miniature 0.375" diameter check valve that is ideal for high pressure hydraulic applications with system pressures up to 5000 psi. This new 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. The maximum restriction when piloted open is only 110 Lohms.

Available in both forward and reverse free flow configurations, the metal components of the valve are constructed entirely of stainless steel for durability and long life.
