Description of the process
The valve allows flow form ② to ③ with very low pressure drop, while blocks flow from ③ to②.
The valve blocks flow form ③ to ② until sufficient pressure is applied at ①.
The valve has a 2.2:1 pilot ratio, meaning that at least 1/2.2 of the load pressure held at ③ is requred at ① to open the valve.
