ZSLD-A3 series electrical signal pneumatic long stroke actuatorDetailed product description：

The ZSLD-A3 series is a pneumatic long stroke actuator powered by compressed air, which receives a 4-20Ma DC signal or a 0.02-0.1MPa air pressure signal given by a regulating unit or manually. The input signal changes to the corresponding displacement (angle or straight stroke), generating proportional adjustment and fast opening and closing two position actions to adjust the air door, baffle, valve, etc. It is one of the important links in automatic regulation systems, widely used in industrial sectors such as power, petroleum, chemical, metallurgy, shipbuilding, and textiles.

This product has the characteristics of simple structure, easy maintenance, low cost, long service life, convenient adjustment, and large output torque.
