A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The CV08-20 allows flow passage from 1 to 2, 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 1 to open to 2.
• Hardened seat for long life and low leakage.
• Optional bias springs for back-pressure application flexibility.
• Fully guided check assembly.
• Compact size.
• Fast closing and seating.
