This is different Actuator with other, what’s our goodness part and first we made 4 racks around the center of the driver shaft was rotated, that’s mean the actuator have more balance, as well it’s smaller than 2-piston actuator, reduced the volume of 1/3 for save installation space, then it gets faster acting cause small volume and shorter piston stroke make air consumption was reduced, moreover duty cycle of up to 200 million times.

We create a special spring technique. The spring is nestled between the piston and the end cap cut out recess, ensuring exact travel direction. There are many potential spring configurations for it because it has four chambers. To avoid winding, three sizes of springs, medium and small, forward and reverse rotation, are grouped together for convenient maintenance.

The piston is constructed of greater mechanical strength, more lasting grade high-strength steel AISI1045, after 7 main method finished, the surface 0.03mm chrome, increased wear resistance and corrosion resistance.

Our cylinders are improve life and stroke shortened compared with conventional cylinders, cause O-ring rubber seals.

Both convex and flat caps are offered in double acting and single acting configurations. High strength aluminum die-casting was used to make the end cap.

Shaft Bearings made of the material having a low coefficient of friction, in order to avoid metal to metal contact.

About cylinder part, interior surface roughness of a cylinder Ra0.4-0.6, 25+m oxide film reduces friction and therefore considerably extends actuator service life, 150m epoxy coating thickness and surface hardness over HV400 provide wear resistance and corrosion resistance.

The cap has a standard NAMUR airport and may be installed immediately with a NAMUR solenoid valve. The drive pinion may be set separately at the start/end point in the 5° rotation range, ensuring perfect placement of all fluid control applications, which means it can be adjusted between 85° and 95°.
