CV50-20 Valve

CV50-20 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 345 bar (5000 psi).

The CV50-20 allows flow passage from 1 to 2, while normally blocking oil flow in the opposite
direction. The cartridge has a fully guided check 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.
• Fully guided check assembly.
• Industry-common cavity.
