HYPC08-30 (Pilot Operated Check Valve)
A cartridge-style pilot-to-open ball--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 3:1 pilot ratio, meaning that at least one-third of the load pressure held at ③ is required at ① to open the valve.
