Valve actuators open and close a valve without manual intervention. They come in three styles: pneumatic, electric and hydraulic, depending on the available source of power. Selection of the right actuator depends on:
- Needed actuation speed
- How frequently it will actuate
- Cycle life
- Need for a manual override or fail-safe
- Whether the valve is in a hazardous environment or not
Neles SC Series linear actuator
Valve positioners sit between the process controller and the valve actuator and adjusts the actuator’s position depending on a control signal. A valve positioner allows you to fine tune your process or speed up your response to changes in the process. They can be used for both linear and rotary valves and come in three styles: Pneumatic, electro-pneumatic and digital.
