Product introduction
Pneumatic actuators are actuators that use air pressure to drive the opening and closing or regulating valves. They are also called pneumatic actuators or pneumatic devices, but they are generally called pneumatic heads.
The actuator and adjustment mechanism of the pneumatic actuator are a unified whole, and the actuators are membrane type, piston type, fork type and rack and pinion type. The long piston stroke is suitable for applications requiring a large thrust; the diaphragm stroke is small and can only directly drive the valve stem. The fork-type pneumatic actuator has the characteristics of large torque, small space, and the torque curve is more in line with the torque curve of the valve, but it is not very beautiful; it is commonly used on high-torque valves. The rack-and-pinion pneumatic actuator has the advantages of simple structure, stable and reliable operation, safety and explosion-proof, etc. It is widely used in power plants, chemical industry, oil refining and other production processes with high safety requirements.
Characteristics
Pneumatic actuators
(1) Air source hole meets NAMUR standard
(2) Aluminum cylinder block, piston and end cap, the lightest weight compared with actuators of the same specification
(3). The cylinder body is extruded aluminum alloy, and the inner and outer surfaces are hard anodized, and the oxidized inner surface has a hard texture, high strength and high hardness. Sliding bearing made of low friction material avoids direct contact between metals, low friction coefficient, flexible rotation and long service life
(4) The surface can be sprayed with different colors.
(5) Adjusting screws at both ends can adjust the opening angle of the valve
(6) The direction can be selected according to the valve needs, rotating clockwise or counterclockwise
(7) Install solenoid valve, positioning device (opening indication), reply device, various limit switches and manual operation device according to user needs
(8) Compact double-piston gear, rack-type structure, precise meshing, high efficiency, constant output torque
