HPC08-30 Valve

HPC08-30 Valve symbol

A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.

The HPC08-30 allows flow from 2 to 3, while normally blocking flow from 3 to 2. Flow will be allowed
from 3 to 2 when pressure at 1 exceeds one-third the pressure at 3.
The cartridge has a 3:1 pilot ratio, meaning that at least one-third of the load pressure held at 3 is
required at 1 to open the valve.
The check is spring-biased to assure holding in static or no-load conditions. A sealed pilot piston
option is available.

• 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%.
