Product Description

AT pneumatic actuator

Mechanical Structure
AT series pneumatic actuators are designed with a double-piston rack and pinion rotating structure. They are divided into double-acting and single-acting (spring return). They are suitable for outdoor or indoor environments that are not corrosive or corrosive.

Advantages of AT pneumatic actuator:
1. Simple structure
2. Large output thrust
3. Smooth and reliable action
4. Safe and explosion-proof
Application field: It is widely used in the production process with high safety requirements such as chemical industry and oil refining.

The AT pneumatic actuator has a long piston stroke and is suitable for occasions requiring greater thrust. It can not only directly drive the valve seat, but also can be used in conjunction with worm gears and so on.

With the continuous development of intelligent pneumatic actuators, intelligent valve positioners have become an indispensable accessory product. The intelligent valve positioner is equipped with a highly integrated microcontroller, which uses the principle of electric balance (digital balance) instead of the traditional force balance principle, and converts electric control commands into pneumatic positioning increments to realize valve position control; use digital open and stop , Off signal to drive the action of the pneumatic actuator; the valve position feedback signal directly passes through the high-precision position sensor to realize the electric/pneumatic conversion function. Intelligent valve positioner has the characteristics of improving output force and action speed, adjusting accuracy, overcoming the friction of valve stem, and realizing correct positioning.
 

Structural characteristics of AT pneumatic actuator

1) The extruded aluminum alloy cylinder body has been hard-oxidized, with hard surface texture and strong wear resistance.

2). Compact dual-piston gear and rack-and-pinion structure, precise meshing, smooth transmission, symmetrical installation position, and constant output torque.

3) F4 guide rings are installed on the movable parts of the piston, rack and output shaft to achieve low friction, long life, and avoid metal-to-metal contact.

4) The cylinder block, end cover, output shaft, spring, fasteners, etc. are all treated with anti-corrosion.

5) The spring of the single pneumatic actuator is preloaded and installed, which can be safely and conveniently disassembled and assembled.

6) AT32 pneumatic actuator can be adjusted in both directions of 0 degree and 90 degree plus or minus 5 degrees in both fully open and fully closed positions.

7). The installation and connection dimensions conform to ISO5211, DIN3337, VD1/VDE3845 and namur standards to ensure interchangeability between AT32 pneumatic actuators and facilitate the installation of solenoid valves, limit switches and other accessories.

8) There are a variety of shapes for the installation and connection holes of the output shaft (square hole, shaft key hole, flat hole) for selection

9) Beautiful and exquisite appearance, light weight, and waterproof sealing structure.

10). There are normal temperature type, high temperature type and low temperature type. Use nitrile rubber under normal temperature working conditions, use fluorine rubber or silicon rubber at high temperature or low temperature

AT pneumatic actuator forms an angle

Standard forming angle: 0°~90°, adjustable ±5°

120°C forming angle: 0° ~120°, adjustable ±5°

180°C forming angle: 0° ~180°, adjustable ±5°

AT pneumatic actuator operating medium

30μm filtered dry or lubricated clean compressed air, or non-corrosive gas. Exposure point temperature -20° (-4°F)

AT pneumatic actuator Air pressure

The maximum air pressure is 10bar (145psi)

The supply air pressure is 3bar(44psi)~8bar(116psi)

AT pneumatic actuator operating temperature

SL is the standard temperature (the sealing material is nitrile rubber O-ring NBR) -20°C (-4°F) ~ +80°C (+176°F)

HL is high temperature (sealing material is fluorine rubber O-ring FPM) -15°C (+5°F)~+150°C (+300°F)

LT is low temperature (sealing material is silicone rubber O-ring SILICON) -40°C (-40°F)~+80°C (+176°F)

For the implementation of low temperature and high temperature, it needs to be lubricated with special grease.
