Lin-E-Aire®閥門(mén)執(zhí)行機(jī)構(gòu)提供最終的精密隔膜電機(jī)控制。這些執(zhí)行機(jī)構(gòu)有氣-下或氣-升兩種類(lèi)型。這兩種類(lèi)型的特點(diǎn)是易于接近的彈簧壓縮螺母，允許容易范圍變化和調(diào)整。
這些執(zhí)行機(jī)構(gòu)采用模壓橡膠膜片與尼龍加強(qiáng)，彈性，易于閥門(mén)行動(dòng)。在執(zhí)行器的整個(gè)行程中，膜片面積的損失不超過(guò)10%，因此在整個(gè)行程中提供了幾乎恒定的力。
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.
