DESCRIPTION A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device. OPERATION 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. FEATURES • 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.
