A cartridge-style pilot-to-openball-type check valve

Technical Feature

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
