Parker Hannifin
Check Valves

They are in-line valves, available in sizes 1/4" to 2", with a pressure rating range of Oto 3000 PSI, f low capacities to 350 GPM, and a variety of crack pressures.

These check valves are specified by design engineers for use in hydraulic systems and on hydraulic equipment world-wide.

Heres why:
All-steel construction-no seal is or gaskets to wearout.

* 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.

* Poppet is heat treated to help prevent damage from shocks, surges and gal I ing.

* 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.

Note: DC SERIES valves are also available with O-ring boss ports in sizes from 114"to I".
