These check valves are specified by design engineers for use in hydraulic systems and on hydraulic equipment world-wide. One-piece body eliminates threads and seals that maybe potential failure or leakage points.
Valve seats resist damage from shocks, surges and contamination.
Poppet has an oil retention groove that I lubricates the bore and eliminates galling. Poppet spring is isolated from the liquid flow stream, minimizing turbulence. Close tolerance fit between poppet and poppet retainer creates a cushion that protects valve from surge shock damage. Check valve body is shaped like an arrowto indicate flow direction. Available in a wide variety of crack pressures.
