Pneumatic ball valveThe structure is a ball and two sealing seats are enclosed in the center of the left valve body and the right valve body. When the sphere is in a closed position, the medium force effect at the upstream end is on the sphere, so that the sphere presses the sealing seat at the downstream end tightly to generate a working specific pressure.

Performance and Selection of Pneumatic Ball Valve

Pneumatic ball valveThe structure is a ball and two sealing seats are enclosed in the center of the left valve body and the right valve body. When the sphere is in a closed position, the medium force effect at the upstream end is on the sphere, so that the sphere presses the sealing seat at the downstream end tightly to generate a working specific pressure. When the working specific pressure is greater than the necessary sealing specific pressure, an effective seal is achieved.
In order to ensure that the ball can generate an effect force of a medium when the ball is in a closed position, it is necessary for the ball of the pneumatic ball valve to be tightly attached to the sealing seat when the pneumatic valve and the pneumatic actuator are assembled in advance, and interference is required to generate a pre-tightening specific pressure, which is the necessary sealing specific pressure for the 0.1 and is not less than 2Mpa. The achievement of this pre-tightening ratio depends entirely on the planned dimensions.
Pneumatic ball valve is used in the process of industry, pneumatic valve to withstand the pressure shake and temperature shake, then the shortcomings of the ball valve is highlighted.
Pneumatic ball valve is the main feature of its own compact structure, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be all or combined.
Pneumatic ball valve is mainly divided into pneumatic ball valve, pneumatic V type ball valve, pneumatic high pressure ball valve, pneumatic fluorine ball valve and other products. Pneumatic ball valve switch light, small size, can be made into a large diameter, reliable sealing, simple structure, easy repair, pneumatic ball valve in more environments can be widely used, can reasonably complete the flow control and regulation effect, to prevent because of uneven flow caused by danger, or lead to the project encountered obstacles.
While feeling the effect of the valve, we should also actively understand the related problems of the pneumatic valve, and select a suitable pneumatic valve to improve the power and value of the operation and reduce the trouble. What factors need to be considered when selecting a suitable pneumatic ball valve:
In the selection of pneumatic ball valve, the first need to consider the use of safety features. No matter what kind of equipment, the use of safe, stable operation is often by our welcome and sought after. The valve is the same. In the process of selection, the operation of the valve can not affect the circulation of the material, and will not be directly touched with water or other liquid objects, to avoid affecting the sealing effect of the valve, which can not accurately complete the effect of the valve.
