①d and smooth movement, high precision, high output power by a simple change in the direction of the piston assembly positions available anti-rotation.
②high quality extruded aluminum alloy cylinder block, by precision machining the hole and the external surface of hard anodized (anodic oxidation under special circumstances +Teflon coating), longer life, low friction coefficient.
③integrated design, all the double acting and singlefunction actuator models have the same cylinder and end caps, easily removed by installing a spring or spring to change the mode of action
④combined pre-spring break Hean whole group, whether in the assembly process or use on-site in both convenient and safe to install or change
⑤the external side of the two single independent adjustment screw has been number of springs. installed in the valve for the actuator is precisely to facilitate, control valve open and
valve closed position, For the whole trip conditioned office is also configured in two cover a longer adjustment screws.
⑥multi-position indicator, on-site visual instructions, consistent with VDI/VDE3845, 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).
⑦gas source interface line NAMURstandard, direct safety plaquesNAMUR standard solenoid valve.
⑧rack on the back of the composite bearing and piston guide ring and the output shaft bearings to prevent metal on metal friction and increasing lubrication, so a low friction,
long life.
⑨All fasteners are stainless steel, long-term corrosion resistance.
⑩connection part of the line with new international standardISO5211,DIN3337 (F03-F25)makes products with interchangeable, versatile.
