Technical Feature
OPERATION:
The valve has a sealed pilot. It allows free flow from port ② to port ① and blocks flow from port ① to port ② or holding a load. Flow will be allowed from port ① to port ② when pressure is applied to pilot ③ .This pilot operated check valve has a 3:1 pilot ratio, meaning that at least one-third of the load pressure held at ① is required at pilot ③ to open the valve. Pressure at port ②directly opposes pilot pressure .
