Q641F stainless steel pneumatic ball valve is mainly used for the media in the truncated or connected piping can also be used for the regulation and control of the fluid, it is compared to other valves, has the following advantages. 
 Q641F stainless steel pneumatic valve structure characteristics 
 1, the fluid resistance is small, ball valves all valves in the fluid path of least resistance, even reduced bore ball valve, the fluid resistance is quite small. 
 2, the thrust bearings to reduce stem friction torque can stem the long-term stable operation and flexibility. 
 3, the seat sealing performance, made of elastic material such as PTFE seals, structure, easy to seal, valve seal ball valve capacity is increasing with the increase of media pressure. 
 Stem seal is reliable, the increase of the stem only for imitation rotation transported without doing the lifting movement, the valve stem packing seal not easily damaged, and the sealing capacity along with increased media pressure. 
 5, Teflon and other materials have good self-lubrication, and the sphere of friction loss is small, so the long life of ball valve. 
 Downloading stem and the stem head is convex order to prevent the stem spray, such as fires caused by the stem seal damage, the convex order and the body can form metal contacts to ensure the stem seal. 
 7, anti-static function: set the spring ball, stem, the valve between the static electricity generated by the switching process can be export. 
 Q641F stainless steel pneumatic ball valve implementing agencies 
 New series of GT type pneumatic actuator, double acting and single acting (spring return), rack and pinion drive, safe and reliable; large diameter valves Series AW pneumatic actuator to pull the fork drive, reasonable structure, output torque, double acting and single acting. 
 A gear dual-piston, output torque, small size. 
 2, cylinder selection of aluminum alloy material, light weight, beautiful appearance. 
 3, can be at the top and bottom of the installation manual operating mechanism. 
 4, the connection of the rack can be adjusted opening angle, the rated flow. 
 5, the actuator optional live signal feedback instructions and all kinds of accessories to automate operations. 
 IS05211 standard connection provides a convenient for the installation of the replacement of the product. 
 7, both ends of the tone section screw allows standard product at 0 ° and 90 ° ± 4 ° of adjustable range. Ensure the synchronization accuracy with the valve.
