2-way valves

2-way control valves regulate the flow of media such as water, steam, or thermal oil. They have an inlet port and an outlet port with flanged or threaded couplings. The flow quantity is controlled by means of an electric, pneumatic, or electro-pneumatic actuator.


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