A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
Product Operation
The CV42-M20 allows flow from ➀ to ➁, while blocking oil flow in the opposite direction.
The cartridge has a fully guided poppet which is spring-biased to 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.• Conforms to ISO 7789 cavity.
