The CV12-21 is a screw-in, cartridge style, hydraulic check valve for use as a blocking or load-holding device
The cartridge valve allows flow passage from port 2 to port 1, 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 port 2 to open to port 1
- Hardened seat for long life and low leakage. Optional bias springs for back-pressure application flexibility. Low check mass for anti-cavitation applications. Cost-effective cavity.
