Single Acting Spring Return Pneumatic Actuator,AT88S
1dual piston rack and pinion design of symmetric structures,rapid and smooth movement,high precision,high output power,by simply changing the position of the piston assembly against the direction of rotation available.
2.Extrusion of high-quality aluminum alloy cylinder block,by the precision machining of the inner hole and outer surface of hard anodized(anodic oxidation under special circumstances+teflon coating),longer life,low friction coefficient.
3.Integrated design,all the dual role and one role of the actuator models have the same cylinder and end caps,easily removed by installing a spring or spring to change the mode of action.
4.Combined pre-safe spring group,both in the assembiy process or use on-site in both convenient and safe to install or change the number of spring.
5.External side of two separate adjustment screw has been installed in the valve on the actuator is precisely to facilitate,control valve open and valve closed position,for a full stroke adjustment when the other two cover a longer adjustment screw office configuration.
6.Multi-position indicator,on-site visual instructions,consistent with VID/VIE3845,NAMUR standard slot,the output can be installed and all the accessories,such as limit switch box,electric positioner,position sensor(pepperl and fuchs,turck).
7.Interface complies with NAMUR standard gas source can be directly mounted NAMUR standard solenoid valve.
8.Rack on the back of the composite bearing and piston guide ring and the output shaft bearings to prevent metal friction and increasing lubrication ,so a low friction,long life.
9.All fasteners are stainless steel,longterm corrosion resistance.
10.Connecting part of the new international standar ds consistent with ISO5211,DIN3337(F03-F25)makes products with interchangeable,versatile.
