How it works
Linear electric actuator
Two-way globe valve
The number that matters
Nominal pressure
25bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.

The three-way mixing/separating control valve is designed to regulate the flow of working media that are not aggressive to the materials of the regulating body by mixing or separating them. The valve is controlled by means of an electric actuator (electric actuator (EIM)). The force developed by the actuator is transmitted through the stem to the plug, which, moving up or down, changes the cross-sectional area in the gate and regulates the flow of the working medium.
