Thermoelectric Valve Actuators and Valve Adaptors for different valve brands

The actuator mechanism utilizes a PTC resistor-heated wax element and a compression spring. When voltage is applied:

• The wax element heats, moving the integrated ram.
• This force is transferred to the valve lifter, opening or closing the valve.
