DIRECTIONAL VALVES

HCV16-20 HyPerformance

Check Valve

DESCRIPTION

A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding

device in high pressure applications.

OPERATION

The HCV16-20 allows flow from 1 to 2, while normally blocking flow in the opposite

direction.

The cartridge has a fully guided poppet which is spring-biased to closed until

sufficient pressure is applied at 1 to open to 2.

FEATURES

• Hardened seat for long life and low leakage.

• Optional bias springs for back-pressure application flexibility.

• All HyPerformance products are tested to the rigorous standards

of the NFPA specification T2.6.1.

• All HyPerformance valves are tested at a verification level of 90%

and an assurance of 99%.
