Thermoelectric Valve Actuators and Valve Adaptors for different valve brands

The actuator mechanism of the A-series actuator uses a PTC resistor-heated wax element and a compression spring.

The wax element is heated by applying the operating voltage and moves the integrated ram.

The force generated by the movement is transferred on the valve lifter and thus opens and closes the valve
