A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The CV10-23 allows flow passage from 2 to 1, while normally blocking flow from 1 to 2. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at 2 to open to 1.
• Hardened seat for long life and low leakage.
• Optional bias springs for back-pressure application flexibility.
• Low check mass for anti-cavitation applications.
• Industry-common cavity.
