Lin-E-Aire® Valve Actuators offer the ultimate in precision diaphragm motor control. These actuators are available in either air-to-lower or air-to-raise types. Both types feature easily accessible spring compression nuts permitting easy range change and adjustment.

These actuators employ molded Buna-N rubber diaphragms reinforced with nylon, for resilient, easy valve action. No more than 10% of the diaphragm area is lost during a full stroke of the actuator, thereby imparting a practically constant force throughout the length of the stroke.
