rack and pinion air rotary actuators auto control butterfly valve
The most popular style of pneumatic actuator consists of a piston and rod moving inside a closed cylinder. Even so, there is a large variety of construction techniques and materials to fit a wide range of applications and user preferences. Body materials can be aluminum, steel, stainless steel and even certain polymers. Construction can be either non-repairable or repairable. This actuator style can be sub-divided into two types based on the operating principle: single acting and double acting.
Single-acting cylinders have a single port to allow compressed air to enter the cylinder to move the piston to the desired position. They use an internal spring or sometimes simply gravity to return the piston to the “home” position when the air pressure is removed. Single-acting cylinders are a good choice when work is done only in one direction such as lifting an object or pressing an object into another object.
Double-acting cylinders have a port at each end and move the piston forward and back by alternating the port that receives the high pressure air. This uses about twice as much energy as a single-acting cylinder, but is necessary when a load must be moved in both directions such as opening and closing a gate.

Pneumatic actuator control valvesstatement of usage and selection
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.
Product Application
AT series Pneumatic Actuator is made of dual pistons driven by racks and pinions. There are two models. One is Dual Acting model, and the other is Spring Return model, which can suit various flammable, corrosive, dusty, strong magnetic field, radiation, vibration corrosive environment indoor or outdoor.
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.
