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.

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.
