AW pneumatic actuator
Features
New valve pneumatic actuators, through optimized and innovative design, adopt new materials and new processes, making the quality and performance of the products more reliable; multi-specification selection is more economical and affordable; the entire series of products are manufactured in strict accordance with the latest standard technical specifications to meet your needs Requirements.
1. Extruded high-quality aluminum alloy cylinder body, the inner hole and outer surface processed by a precision machining center are hard anodized.
2. The structural design of the double-piston gear rack is high in precision, fast and stable, and has a long service life. The cylinder rotation direction can be changed on site by simply changing the assembly position of the piston.
3. The two external independent stroke adjustment screws can be adjusted conveniently and accurately +/-5° in two directions to keep the actuator consistent with the valve position in the fully open and fully closed positions.
4. The universal, anti-fracture, nickel-plated output gear shaft can easily convert between octagonal and round shaft holes, making it easier to prepare materials and more flexible.
5. One-piece compact design, both double-acting and spring-return single-acting actuator models have the same cylinder, piston, and end cover, reducing product spare parts and allowing on-site conversion by adding or removing springs.
6. Multifunctional position indicator, on-site visual indication, can install all accessories conveniently and simply.
7. Combined reserved spring seat and unique O-ring seal design, suitable for various occasions, safer and more corrosion-resistant.
8. High-precision tooth shapes on gears and racks: making the gearing gap of gears and racks smaller and more precise, and increasing the output power.
9. Choose a high-quality support ring to reduce the friction coefficient of the O-ring, have a long service life and a wide operating temperature range.
10. Internal and external stainless steel standard parts with long-term corrosion resistance.
11. Comply with the latest international standards: ISO5211, DIN3337 and VDI/VDE3845 and have good interchangeability, which facilitates the installation and use of solenoid valves, limit switches and other accessories.
working principle
Double acting actuator
The "A" port takes air in, and the compressed air pushes both ends of the piston to move, causing the actuator output shaft to rotate counterclockwise (0°-90°), and the "B" port exhausts.
The "B" port takes air in, and the compressed air pushes the piston to move in the middle, causing the actuator output shaft to rotate clockwise (90°-0°), and the "A" port exhausts.
Single acting actuator
Air is taken in at port "A", and the compressed air overcomes the spring force and pushes both ends of the piston to move, causing the actuator output shaft to rotate counterclockwise (0°-90°), and is exhausted at port "B".
When the actuator is cut off, the piston moves to the middle under the action of the spring force, causing the actuator output shaft to rotate clockwise (90°-0°), and the "A" port is exhausted.
Selection
When selecting a pneumatic actuator, add a safety value to the determined torque of the valve. For water vapor or non-lubricated liquid media, increase the safety value by 25%; for non-lubricated slurry liquid media, increase the safety value by 30%: for non-lubricated dry gas The medium increases the safety value by 40%: the non-lubricated granular powder medium transported by gas increases the safety value by 60%: the clean, low-friction lubricating medium increases the safety value by 20% (for reference only).
