Electro-thermal actuator

The valve actuator is 2-point controlled and is electro-thermally operated. It can be mounted on zone valves and manifolds using its flare nut. With factory default setting and in its non-voltage state the actuator keeps the valve closed, while it opens the valve in response to 230V voltage in a couple of minutes. If required, its operation can be easily inverted to keep the valve opened in its non-voltage state. The open or closed position of the valve is indicated by the axial displacement/position of the pin located on the front panel of the actuator. In closed position the pin sinks into the front panel, in opened position the pin raises some millimeters above the front panel. The simple electro-thermal construction ensures reliable operation and low energy consumption.
