KLINGER Die Erste offers valve actuators as well as actuator accessories, including pneumatic actuators, electric actuators, solenoid valves and limit switches.
Depending on the flow requirements of the industrial process system, some method of changing the positions of valves is needed. Some valves are operated with hand wheels or levers. Other valves must be open, closed, or throttled frequently. Manually positioning valves in these types of situations is not practical and instead of using hand wheels or levers to control actuation, automated valve solutions such as using a valve actuator for positioning the valves.
A valve actuator is a mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil).
Solenoid valves, also known as an electrically-operated valve, are used wherever fluid flow has to be controlled automatically. Solenoids operate using an electromagnetic solenoid coil to change the state of a valve from open to closed, or vice-versa.
Limit Switches are activated by cams connected to the actuator shaft. When activated, they indicate the actual valve position and confirm that a that a valve has been fully opened or closed remotely.
