CV50-20 Check Valve, High Pressure (CV50-20)
A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device for high pressure applications.
Product Operation
The CV50-20 allows flow passage from ➀ to ➁, while normally blocking oil flow in the opposite direction.
The cartridge has a fully guided check which is spring-biased closed until suffi cient
pressure is applied at ➀ to open to ➁
Product Features
• Hardened seat for long life and low leakage.
• Optional bias springs for back-pressure application flexibility.
• Fully guided check assembly.
• Industry common cavity.
