CHECK VALVE

Overview

Description

The HCV08-20 is a screw-in, cartridge style, hydraulic check valve for use as a blocking or load-holding device for high pressure applications.

Operation

The check valve allows flow from port 1 to 2, while normally blocking flow in the opposite direction. The cartridge valve has a fully guided poppet which is spring biased closed until sufficient pressure is applied at port 1 to open to port 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.
  • 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%.
