Devices designed to automatically control and monitor the position of valves, in relation to their open or closed positions.
Valve Actuators and Positioners Categories
Electric Valve Actuators (407 suppliers)
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
Electrohydraulic Valve Actuators and Hydraulic Valve Actuators (131 suppliers)
Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion.
Manual Valve Actuators (90 suppliers)
Manual valve actuators do not require an outside power source. They use a handwheel or lever to drive a series of gears whose ratio results in a higher output torque compared to the input (manual) torque.
Pneumatic Valve Actuators (430 suppliers)
Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion.
Valve Actuators (864 suppliers)
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
Valve Position Indicators (63 suppliers)
Valve position indicators are devices that show the position of the closure element.
Valve Positioners (191 suppliers)
Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves.
