Pneumatic flanged stainless steel ball valve

Pneumatic flanged stainless steel ball valve introduction：
Pneumatic flanged stainless steel ball valve is a ball with a circular hole for opening and closing parts, the ball with the ball valve stem rotation, in order to achieve the opening and closing action of the pneumatic ball valve,Pneumatic flanged stainless steel ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium,Pneumatic flanged stainless steel ball valve only needs to be rotated 90 degrees of operation and very small torque can be closed tightly.Completely equal body cavity for the medium to provide little resistance, through the flow.

Pneumatic flanged stainless steel ball valve is not only simple structure, good sealing performance, and within a certain range of nominal pass after small volume, light weight, less material consumption, installation size is small, and the drive torque is small, easy to operate, easy to realize the rapid opening and closing, easy operation and maintenance,Pneumatic flanged stainless steel ball valve is suitable for water, solvents, acids and natural gas and other general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene.

The main features of Pneumatic flanged stainless steel ball valve are as follows:
1. Pneumatic flanged stainless steel ball valve fluid resistance is small, with the lowest flow resistance (in fact, zero), pneumatic ball valves generally have reduced diameter and full size two structures.Regardless of that kind of structure,Pneumatic flanged stainless steel ball valve flow resistance coefficient is relatively small.In particular, the so-called full flow type, that is, the diameter of the ball valve, because its channel diameter is equal to the pipe diameter, local resistance loss is only the same length of the friction resistance of the pipe, that is, in all valves, the flow resistance of this pneumatic ball valve is the least.
2. Pneumatic flanged stainless steel ball valve opening and closing switch is fast and convenient, because the ball valve in general only need to turn the handle 90° to complete the full open or close action, it is easy to achieve fast opening and closing.It can realize fast opening and closing, and the opening and closing time of some structures is only 0.05 ~ 0.1s, so as to ensure that it can be used in the automation system of the test bench.Quick opening and closing valve, no impact in operation.
3.Pneumatic flanged stainless steel ball valve sealing performance is good, at present, the seat of the vast majority of pneumatic ball valve is made of polytetrafluoroethylene and other elastic materials, metal and non-metallic materials of the sealing pair, usually known as soft seal.Generally speaking, the sealing of soft seal is easy to guarantee, and the machining precision and surface roughness of the seal surface are not very high.
4. Pneumatic flanged stainless steel ball valve service life is long, due to PTFE has good self-lubrication, and the friction and wear of the ball is small, and because of the improvement of the ball processing technology, the roughness is reduced, thus improving the service life of the ball valve.According to the standard field valve company in the laboratory on the ball valve life test, the number of switching more than 100,000 times.
5. Pneumatic flanged stainless steel ball valve ball closure can be automatically positioned in the position, and can withstand the high pressure difference when closed.
6. Complete bidirectional sealing of Pneumatic actuator actuated ball valve can be achieved within the range of earth pressure and temperature.
7. When Pneumatic flanged stainless steel ball valve fully open and fully closed, the sealing surface of the ball and valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause the erosion of the sealing surface.
  
Pneumatic flanged stainless steel ball valve installation：
1) Remove the protection cover on both sides of the flange end and rinse the Pneumatic flanged stainless steel ball valve when it is fully open.
2) Before Pneumatic flanged stainless steel ball valve installation, the complete machine shall be tested according to the specified signals (electricity or gas) (to prevent vibration affecting the performance due to transportation), and on-line installation shall be carried out after passing (wiring shall follow the circuit diagram of electric actuator).
3) Flush and remove any remaining impurities (which may damage the seat and ball) from the pipe before preparing to connect with the pipe.
4) During installation, please do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories..
5) Pneumatic flanged stainless steel ball valve shall be installed in the horizontal or vertical direction of the pipeline.
6) The pipeline near the installation point should not sag or bear external forces. Pipe supports or supports can be used to eliminate the deviation of the pipeline.
7) After connecting with the pipe, cross lock the flange connection bolt with the specified torque.
