A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device for high pressure applications.
The HCV12-20 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.
• Cost effective cavity.• All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
