ATseries pneumatic actuators are developed, developed and designed on the basis of comprehensive use of new technologies, new materials, new processes and innovative ideas at home and abroad.Ithas the following characteristics: Fully comply with the latest international specifications: ISO5211, DIN3337andVDWDE3845, NAMURstandards. *Extruded high-strength hard cylinder block, the inner surface is finely ground and hard anodized,with long service life, low friction coefficient and rapid action. *Beautiful, compact, modern shape, multi-specification series of products make the selection more economical and affordable. •*All movable surfaces are made of high-quality bearings. Low friction, long life, no noise. *Two independent stroke adjustment mechanisms are installed externally.It is convenient to adjust the ±5° fully open or fully closed position at the time. * Actuators with the same external structure are available in double-acting and single-acting (spring return), and single-acting types are normally closed and normally open. *NAMURstandard multi-function position indicator can visually indicate, install and output all accessories. *Pre-compressed load spring.Installationanddisassembly are safeand convenient. *The piston and end cap are made of pressure bell aluminum alloy, which has high strength and light weight. *Change the material of the seal,which can be applied to high or low temperature occasions. *According to needs, a variety of angular strokes (for example: 120°, 135°, 180°, etc.) and three-position pneumatic actuators can be provided.No need to connect the board, butInstall electromagnetic directly.
