Product Description
Single Phase Quarter Turn Electrical Actuator
SDtork Electric Actuator type 1000 series have been designed for remote control of Ball Valves Butterfly valves Dampers and other actuating devices which require up to 90° rotary actuation and tight closure in end positions. They are simple in design with compact in size and lighter in weight due to high grade aluminium alloy housing.
