Product Description

Pneumatic Actuator
New rack and pinion pneumatic actuator by the Avannto company ccmbines the latest technology at home and abroad, through the three-dimensional model of innovation and optimization of CAD design, beautiful shape compact, modem styling; and adopt practical new materials, new processes, so that the product quality, more reliable; more standard selection of more affordable; products fully meet the latest intemational standards, technical speciffcations, to meet current and future needs.
1. Dual piston rack and pinion design of symmetric structures, rapid and smooth movement, high precision, high output power by a simple change in the direccion of the piston assembly positions available anti-rotation 
2.High quality extruded aluminum alloy cylinder block, by precision machining the hole and the extermal surface of hard anodized (anodic oxidation under special circumstances+ PTFE coating), longer life, low friction coefficient.
3.integrated design, all the double acting and single-function 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-spring break Hean whole group, whether in the assembly process or use on-site in both convenient and safe to install or change the 
5.The 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. 
6.Multi-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, posion sensor (Pepperl and Fuchs, Turck) 
7.Gas source interface line NAMURstandard, direct safety plaquesNAMUR standard solenoid valve. 
8.Rack 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.
9.All fasteners are stainless steel, long-term corrosion resistance 
10.Connection part of the line with new international standard 1S05211, DIN3337 (F03-F25) makes products with interchangeable, versatile.
