A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The CV12-20 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
• Hardened seat for long life and low leakage.
• Optional bias springs for back-pressure application flexibility.
• Fully guided check assembly.
• Cost effective cavity.
