Stainless Steel Rotary Pneumatic Actuator for Ball Valve and Butterfly Valve

316 and 304 stainless steel pneumatic actuator has electro-chemical polishing on surface and great anti-corrosion performance, which is quite suitable to be applied in high corrosion-resistance working environment.

Stainless steel pneumatic actuator has various advantages as following:

1)Double piston rack and pinion design, reasonable structure, symmetric assemble position, easy rotation of output shaft, long service life and rapid motion

2)Composite bearing on piston and guide ring on shaft reduces friction and prolongs serivce life

3)Combined preloading coating springs has strong corrosion resistance and can prolong service life

4)Small mesh gap, high precision and large output torque rack and pinion

5)Great anti-corrosion and safe stainless steel fasteners

6)International Standard Size:

A.Top connection size complies with NUMAR standard;

B.Air supply connection size complies with NUMAR Standard;

C.Bottom connection size is in line with ISO 5211 and DIN 3337 standard;

All these standard size make it easy to assemble solenoid valve, limit switch box, positioner, etc.
