W-Actuators

These electro-thermal actuators may be used for the automatic control of the shut-off valves. When the actuators are mounted on the cranes, they automatically shut off the water from the boiler. As soon as there is a heat demand of the heating system, the thermostat, which is in communication with the receiver, sends a signal for the actuators to open the valves. When the correct temperature is reached, they close the shutoff valves again.
