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.

Stainless steel microflow control valve baelz 185

Versatile, multipurpose stainless steel microflow control valve for fluids and steam, ideal for low flow rates.

Control valve baelz 340

Two-way control valve in a three-way body for liquids and gaseous media in industrial applications. Several plug types available, depending on the control task. In the EMF version: balanced valve; the forces on the valve plug are compensated by a balancing surface, so a less powerful actuator is sufficient.

Control valve baelz 340 with cooling tube

Two-way control valve in a three-way body with cooling tube for liquids and gaseous media in industrial applications. Several plug types available, depending on the control task. The cooling tube allows it to be used at higher temperatures. Valves with cooling tube and stainless steel bellows are suitable for use with thermal oil. In the EMF version: balanced valve; the forces on the valve plug are compensated by a balancing surface, so a less powerful actuator is sufficient.
