PILOT OPERATED CHECK VALVE

Overview

Description

The HPC08-30 is a screw-in, cartridge style, pilot operated, hydraulic check valve for use as a blocking or load-holding device for high pressure applications

Operation

The valve allows free flow from port 2 to port 3, while normally blocking flow in the reverse direction. Flow will be allowed from port 3 to port 2 when pressure at port 1 exceeds one-third the pressure at port 3

Features

  • Hardened seat for long life and low leakage.
  • Optional sealed piston.
  • Optional spring ranges.
  • Compact size.
  • 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%.
