1、It has the characteristics of large torque, small space, more in line with the torque curve of the valve and so on, but not very beautiful, which is commonly used in valves with large torque.
2、The wall of the cylinder body is plated with hard lead polishing or Teflon coating, and the piston rod is plated with hard wax polishing with good abrasion resistance; bearings not lubricated with oil and the guide rings are equipped between all the sliding parts to reduce the friction coefficient and prolong the service life.
3、The output torque of series of pneumatic actuator with U type curve characteristic is more suitable for large diameter ball valve, the switch and adjustment of butterfly broad, and other 90 degree rotating occasion.
