3 Way Pneumatic Diaphragm Control Valve

Valvesonly is the topmost 3 way pneumatic diaphragm control valve manufacturer in USA. A 3 way pneumatic diaphragm control valve is a valve with three ports used to control fluid flow. It utilizes a diaphragm actuator powered by compressed air for regulation.

A 3 way valve has three ports: one inlet and two outlets (or vice versa). It’s used to divert or mix fluid flows as needed.

Diverting Flow In one mode, the valve directs flow from the inlet to one of the outlets while closing off the other outlet. The diaphragm actuator controls the valve’s position to achieve this diversion.

Mixing Flow In the other mode, the valve lets fluid from two inlets mix before exiting through a single outlet. The diaphragm actuator adjusts the valve to regulate the mixing ratio. Compressed air moves the diaphragm, changing the valve’s internal structure and consequently controlling the flow direction and rate.

Valvesonly is a top 3 way pneumatic diaphragm control valve manufacturer in USA. It Controls flow via diaphragm actuator & 3 ports. Diverts or mixes fluid for versatile control in processes.
