AT Pneumatic Flanged Ball SUMMARY
AT pneumatic flanged ball valves pneumatic actuators using the new AT / GT Series pneumatic actuators, the structure of the State utility model patents, double-acting and single-acting (spring return), the gear rack structure Transmission, performance more secure and reliable. 
 
 First, AT Pneumatic Flange Ball Valve Introduction
 AT pneumatic flange ball valve pneumatic actuator with a new AT / GT series of pneumatic actuators, the structure of the national utility model patents, double and single acting (spring reset), the use of gear teeth Bar structure transmission, more secure and reliable performance; large diameter valve with AW series of pneumatic actuators, fork-type structure of the transmission, reasonable structure, the output torque. 
 AT pneumatic flange ball valve with a second time off the ball valve, with explosion-proof device, available gas cut off. It is composed of ball valve and single acting piston type pneumatic actuator. It is widely used in the fields of natural gas, oil, chemical, metallurgy, papermaking, mining, printing and dyeing, biopharmaceutical, household chemical, food and beverage, water treatment and air treatment Of the fluid cut off control, and supporting the use of automated pneumatic instruments. 
 
 Second, AT Pneumatic Flange Ball Valve Works
 AT aerodynamic flange ball valve from the valve body, ball, valve shaft, seal ring, packing, pressure plate and other components. The actuator is composed of main components such as gas, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bearing, adjusting bolt and so on. The actuator is connected to the valve connection shaft. The cylinder input air pressure, the role of the piston to produce a certain thrust, so that the gear-type output in the piston driven, the gear output shaft rotation, driven valve shaft rotation, so that the ball ball in the valve with the rotation, change the valve Circulation area, to achieve the purpose of changing the flow through the valve medium. 
 
 Third, AT Pneumatic Flange Ball Valve Features
 1, Thrust bearings to reduce the stem friction torque, the stem can be long-term operation smooth and flexible. 
 2, The valve seat sealing performance, the use of PTFE and other elastic materials made of seals. 
 3, Anti-static function: in the sphere, stem, valve body set between the spring, the switch can produce static electricity derived.
 4, Stem seal is reliable, because the stem only for the rotation and movement without lifting movements, stem packing seal is not easy to damage. 
 5, Due to PTFE and other materials with good self-lubricating, and the ball friction loss is small, so the long life of the ball valve. 
 6, Cutting speed, with a second time cutting capacity, and sealing performance, can be equipped with explosion-proof device, available gas pipeline cut off.
