Lin-E-Aire®阀门执行机构提供最终的精密隔膜电机控制。这些执行机构有气-下或气-升两种类型。这两种类型的特点是易于接近的弹簧压缩螺母，允许容易范围变化和调整。
这些执行机构采用模压橡胶膜片与尼龙加强，弹性，易于阀门行动。在执行器的整个行程中，膜片面积的损失不超过10%，因此在整个行程中提供了几乎恒定的力。
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.
