Valve actuator
CWG series
Outline
The CWG series motors are economic and compact worm gear reducers for general industries, such as water supply and sewerage systems, iron, and steel that were developed as manual operation devices for various kinds of devices, such as valves for 90-degree rotation, including butterfly valves and ball valves.
In addition, combining the CWG series worm gear reducer and our electric operation device enables electric operation.
Features
- – The double sleeve structure facilitates easy changes of the key position relative to the valve stem.
- – The rotational direction and position of the input shaft can be chosen freely.
- – The double seal structure of the terminal block protects the electrical room.
- – The dustproof and waterproof performances correspond to IP67.
- – The stopper angle is variable by +/- 5 degrees at both travel ends.
