A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device. Available in conventional surface mount or convenient “down-hole” versions.
The CV04-20 and CV04-B20 allow 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.• Miniature size.• Fast closing and seating.
