Air Operated Butterfly Valve By Spring Return Double Acting Pneumatic Actuator

AT Series pneumatic actuators offer a simple and cost effective solution for your valve automation needs. For use on quarter turn (90°) ball valves and butterfly valves. The dual, opposed rack pistons have low friction bearings and guides that provide high-performance, long cycle-life, and fast response. These pistons can be inverted to reverse the rotation for fail open applications.These are rack and pinion style actuators 

Pneumatic Actuator

Main Features

Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.

The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.

Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.

All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise

The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.

Same outline actuators have the functional modes of double acting and single acting (Spring -Return). The Spring-Return has the normally-open and normally-close styles.

Multi function indicator with NAMUR is convenient for mounting accessories.

Pre-compressed load spring is convenient for safe mounting and tear down procedures.

Die-casting aluminum pistons and end caps have high intensity and light weight.

Different O-rings materials are available for high and low temperature.

Solenoid valves are easily mounted without any connecting plank.

Auto-control in the field of electric power, petrochemical, metallurgy, petroleum, gas, town, construction, drainage, chemical industry, oil refining, mining, power plant, metallurgy, architecture, medicine, food, gas, scientific research, etc.
