The 3-way pneumatic diaphragm control valve is composed of diaphragm actuators with multiple guided springs, cage-type regulating mechanism and intelligent integrated positioner. The valve spool adopts cylindrical thin-walled window design and is guided on the side; it has two outlets, one is open when the other is closed. The valve design permits less pressure loss, large flow capacity, low noise and small unbalanced force, and adapts to large differential pressure. It has the advantages of compact structure, high control accuracy, accurate flow coefficient, stable and reliable performance, etc, and suits for two-phase control and simple ratio adjustment of heat exchangers. The valve is always used to get rid of the solution of two two-way valves + one Tee for some cases.
