3-way valves

Depending on version, 3-way valves have three flanged or threaded couplings via which the volume flows enter and/or exit. They are used as mixing or diverting valves. The flow quantity is usually controlled by means of an electric, pneumatic, or electro-pneumatic actuator.

With a three-way mixing valve (2 inlets and 1 outlet), media at two different temperatures flow into the valve, where they are mixed before exiting via the third port.

With a diverter valve (1 inlet and 2 outlets) the incoming volume flow is usually distributed to the two outlet ports.

3-way valves from Baelz are suited to a wide range of applications. They can be used for water, hot water or thermal oil and stand out due to their superior versatile design.
