A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device for high pressure applications.
The HCV08-20 allows flow passage from 1 to 2, while normally blocking oil flow in the opposite direction.
The cartridge valve has a fully guided poppet which is spring-bias 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.
• All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%
