Overview of AT pneumatic flanged ball valves
 
      AT pneumatic valve pneumatic actuator using our new AT/GT series of pneumatic actuators, the structure of national utility model patents, there are double and single acting type (spring), with rack and pinion drive structure, the performance is more safe and reliable.
 
 One: AT pneumatic valve profile method in basketball
       AT pneumatic valve pneumatic actuator using our new AT/GT series of pneumatic actuators, the structure of national utility model patents, there are double and single acting type (spring), with rack and pinion drive structure, the performance is more safe and reliable; large diameter valves using AW series pneumatic actuator, fork the transmission type structure, reasonable structure, large output torque.
 
       AT pneumatic flanged ball valve has one second time to cut off the ball valve. It is equipped with explosion-proof device and can be cut off by gas. Is the ball valve and single acting piston pneumatic actuator which is widely used in natural gas, oil, chemical industry, metallurgy, papermaking, printing and dyeing, office electric mining, bio pharmaceutical, daily chemicals, food and beverage, water treatment and air treatment industry cut off control, and automatic pneumatic instrument supporting the use of.
 
 
Two: AT pneumatic flange ball valve working principle
 
      AT pneumatic flanged ball valve consists of valve body, sphere, valve shaft, seal ring, packing, pressure plate and other components. The actuating mechanism is composed of gas, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bush, adjusting bolt and other main components. The actuating mechanism is connected with the connecting shaft of the valve. The cylinder pressure input, acting on the piston to produce certain thrust, the gear type output in piston driven gear output shaft to rotate the valve, drive shaft rotation, so that the ball valve in the valve with the rotation, change the valve flow area, to change the media flow through the valve to.
 
 Three: AT pneumatic flanged ball valve product features
 1 、 thrust bearings reduce the friction torque of the stem, so that the valve stem can be operated stably for a long time.
 2, The valve seat sealing performance is good, using PTFE and other elastic material made of sealing rings.
 3, Antistatic function: a spring is arranged between the ball, the valve stem and the valve body, so that the static electricity generated by the switching process can be exported.
 4, The stem seal is reliable, because the stem only for rotating and moving without lifting movement, stem packing seal is not easy to destroy.
 5, Because PTFE and other materials have good self lubrication, and ball friction loss is small, so long service life of the ball valve.
 6, Cutting speed, with a second time cutting capacity, and good sealing performance, can be equipped with explosion-proof devices, gas pipes can be cut off.
