Introduction of straight stroke pneumatic actuator Manufacturer Introduction of single acting pneumatic actuator
Single acting pneumatic actuator is a kind of pneumatic actuator, which has double piston rack and gear rotating structure. The piston type has a long stroke and is suitable for the occasion with large thrust. It can not only directly drive the valve stem, but also cooperate with the worm gear.
Optional intelligent valve positioner, solenoid valve, limit switch of echo device, handwheel mechanism, air filter pressure reducing valve, etc.
In the production process of chemical industry and oil refining, in the process of simple structure, the structure is simple, the output thrust is large, the action is stable and reliable, and it is safe and explosion-proof. Scope of application: ball valve, butterfly valve, etc
Performance characteristics of single acting pneumatic actuator:
1. Indicator
The indicator conforms to VID/VIE3845NAMUR limit switch, positioner and other accessories, which are easy to install.
2. Output shaft
The design of nickel plated alloy steel integral forging output shaft meets the requirements of NAMUR, ISO5211.DIN3337 standards. Special standards can be customized according to customer requirements.
3. Cylinder block
Teflon coating is extruded from high-quality aluminum alloy, and the surface is hard anodized.
4. End cover
Aluminum alloy die-casting, surface anodizing, metal polyester coating.
5. Piston
Hard oxidation treatment of cast aluminum
6. Adjusting bolt
Two independent stroke adjusting bolts can be convenient and accurate ± 5. Adjust the opening and closing angle of the valve.
7. Spring
High quality spring steel is used for preloading assembly. The number of springs can be easily disassembled or changed to meet different torque output ranges.
8. Piston ring
The composite material with low friction and long service life is used, which is convenient for maintenance and replacement.
9. Sealing
Dingyueqing rubber is used at room temperature, and special seals are used at high and low temperatures.
10. Air source interface
NAMUR compliant standard NAMUR solenoid valve can be directly installed.
11. All fasteners are made of stainless steel
