The combination of rotating drive system and the worm gear unit was a success of our special reversing valve. It offers the selection of moving periods and moving forces for all armature sizes and operation conditions in optimum.
The electric motor drives via worm gear the shaft of the valve. Just in time, after arrival of the switched end position the rotating will be stopped by the limit switch. After the end of the remaining time defined in the reverse position it follows the way back to the normal flow automatically.
Pneumatic actuators or Electric actuators with fail-safe spring return are available on request.
