The pneumatic diaphragm three-way regulating valve has two modes of action: confluence and diversion. The valve core structure adopts a cylindrical thin-walled window and a valve core side guide. The three-way valve can replace two two-way valves and a three-way pipe in some occasions and is widely used. It is often used for two-phase regulation of heat exchangers and can also be used for simple ratio regulation.
