, the pneumatic actuator all fastening pieces are made of stainless steel materials, long-term corrosion.

2, the pneumatic actuator gas interface conforms to the NUMAR standard, can be directly installed NAMUR standard solenoid valve.

3, the connection part accord with the standard of international new IS05211, DIN3337 (F03-F25) to make the product installation has interchangeability, universality.

4, the combined pre load safety spring group, no matter in the assembly process or using the site, can install or increase or decrease the spring quantity is convenient and safe.

5, gear rack type double piston symmetrical structure design, rapid action, stable, high precision, large output power, anti rotation direction can be obtained by changing the position of the piston assembly simple.

6, the rack on the back of the composite bearing and piston guide ring and the output shaft with bearing to prevent the friction of metal on metal, and increase the lubrication, the low friction, long life.

7, integrated design, double acting and all single acting actuator model, all have the same cylinder and end cover, very convenient installation or removal by spring spring to change the mode of action.

High quality aluminum alloy cylinder block 8, extrusion processing, l special case of anodic oxidation + Teflon coated hard anodic oxidation by the precision machining of the inner hole and the external surface). The service life is longer, lower friction coefficient.

9, multi functional position indicator lamp, scene visualization instruction, comply with VDI/VDE3845, NAMUR standard slot, can install and output all accessories, such as limit switch box, soap pneumatic positioners, position sensor f Pepperl + Fuchs, ring Schalke).

10, the pneumatic actuator external side of two separate adjustment screw for actuator installed in the valve is more accurate and convenient, regulating valve opening and closing of valve position. For a full stroke adjustment is also in the two end covers a longer adjustment screw configuration.
