LIN-E-AIRE® Pneumatic Valve Actuator
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.
Lin-E-Aire Specifications
- Air Supply Connection:1/4″ NPT.
- Temperature Limit:150°F (66°C).
- Materials of Construction:Diaphragm: molded Buna-N rubber, nylon reinforced; Diaphragm Support Plate: plated steel; Spring: plated spring steel; Push Rod: plated cold rolled steel; Housing: drawn steel with baked enamel finish; Yoke: cast iron with baked enamel finish; Spring Adjustment: plated cold rolled steel, ball thrust bearing.
CAUTION: Use of an actuator supply gas other than air can create a hazardous environment because a small amount of gas continuously vents to atmosphere.
