HYPC10-30 (Pilot Operated Check Valve)

Description:
A cartridge-style pilot-to-open poppet--type check valve.

Operation:

The valve allows flow from ② to ③, while normally blocking flow from ③ to ②.

Flow will be allowed from ③ to ② when sufficient pressure is applied at ①.

The cartridge has a 3.5:1 pilot ratio, meaning that at least 28 percent of the load pressure held at ③ is required at ① to open the valve.
