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.
