Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion

Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source

Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion

Manual valve actuators do not require an outside power source.

Vacuum valves are used when a vacuum must be maintained in a closed system

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line

Air valves allow metered fluid flow in one or both directions.
