Useful device for valve positioning and control
Mounting switches are in practice not a problem for 90 degree valves, but difficulties may arise with gate and globe valves, and here the solution is the Netherlocks Posimech
Locking and unlocking are both fully mechanical.
The system uses a lock cylinder that releases a key only when the door, fence, sleeve or valve is fully in the safe position.
After this step the operator or maintenance engineer is able to access the machine.
Thanks to the use of mechanical key transfer all wire-related equipment can be eliminated, thereby reducing maintenance.
This is a very important advantage for the heavy industries, and Netherlocks wireless switches can be completely maintenance free in applications such as pulp and paper, electrical precipitators, robots, and the paint, cement and petrochemical industries.
In addition, with no wires, savings can be made on installation and safety certification.
For further applications flexibility, the locks can be combined with solenoids or mechanical time delays.
