Pneumatically operated quarter turn valves and valves with linear actuator are often used in conjunction with electrical position indicators.
Latest generation
Dependent on the device type, either microswitches or proximity switches are used. They enable reliable end position feedback and can be equipped with a field bus connection upon request (e.g. AS-Interface, DeviceNet etc.). The latest generation is self-learning. These devices recognize the valve end positions by means of manual or automatic end position programming during initialization. No time consuming manual setting of microswitches or proximity switches is necessary, retrofitting to installations or recalibration after servicing work becomes considerably easier.
