Shanghai double high valve double acting pneumatic flange ball valve, Hunan Shanghai double high pneumatic ball valve
Q641F pneumatic flange ball valve
Features and uses
It is mainly used to truncate or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. Compared with other valves, it has the following advantages.
1, the fluid resistance is small, the ball valve is the least fluid resistance in all types of valves, even if the ball valve, its fluid resistance is very small.
2 and thrust bearings reduce the friction torque of the stem, which can make the long operation of the stem smooth and flexible.
3, the valve stem seal is reliable, because the stem only for imitation rotation transported without movement, stem packing seal is not easy to damage, and sealing ability increased with the increase of the pressure medium.
4, the valve seat seal performance is good, uses the polytetrafluoroethylene and other elastic materials to make the sealing ring, the structure is easy to seal, and the ball valve sealing ability increases as the medium pressure increases.
5, because of the good self lubrication of polytetrafluoroethylene and other materials, the friction loss of the valve and the ball is small, so the service life of the ball valve is long.
6, downloading the stem and the stem head convex order to prevent the stem spray, such as stem seal damage caused by fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.
7. Antistatic function: the spring is set between the ball, the valve stem and the valve body, which can produce the static electricity produced by the switch process.
Executive Agency
Using the new GT series of pneumatic actuators, a double acting and single acting (spring), gear rack drive, safe and reliable; AW series of large diameter valves using pneumatic actuator fork transmission, reasonable structure, large output torque, a double acting and single acting.
1, the gear type double piston, the output torque is big, the volume is small.
2, cylinder selection of aluminum gold material, light weight, beautiful appearance.
3, the manual operation mechanism can be installed at the top and bottom.
4, the rack type connection can adjust the opening angle and the rated flow.
5, actuator's optional charged signal feedback instructions and all kinds of accessories are used to automate the operation.
6, the IS05211 standard connection provides convenience for the installation and replacement of the product.
7. The joint screws at both ends can make the standard products in 0 and 90 degrees with an adjustable range of 4 degrees. Ensure synchronous precision with valve
