Actuator
Actuators open and close industrial valves automatically. By removing the need for manual operation, they make processes safer and more efficient.
Limit switch box
Limit switch boxes are used in industrial automation to monitor the position of a valve or another moving mechanical part. They are usually combined with pneumatic and electric actuators, and can also be mounted directly on a manually operated valve.
Manual gear operator
Manual gear operators make it possible to operate large, high-torque valves by hand. The operator turns a handwheel or lever, and the gear mechanism opens or closes the valve.
