A cartridge-style Pilot to open, poppet-type check valve

Technical Feature

OPERATION:
The valve allows flow from ② to ① , while normally blocking flow from ① to ② . Flow will be allowed from ① to ② when sufficient pressure is applied at ③．
The cartridge has a 3:1 pilot ratio, meaning that at least one-third of the load pressure held at ① is required at ③ to open the valve.
