HCV42-M20 Valve

HCV42-M20 Valve symbol

A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device in high
pressure applications up to 350 bar (5075 psi).

The HCV42-M20 allows flow passage from 1 to 2, while normally blocking oil flow in the opposite
direction. The cartridge has a fully guided poppet which is spring-biased closed until sufficient
pressure is applied at 1 to open to 2.

• 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%.
