Pneumatic ball valve model preparation method

Pneumatic ball valve model preparation method/code name establishment in China.
With the rapid development of my country’s industrial modernization, the use of valves is also increasing. Pneumatic ball valves have the advantages of fast opening and closing speed, and not only can switch and cut off, but also control flow, etc., and become the most widely used valve type. one! However, due to the wide variety of pneumatic ball valves, including the use of pressure, temperature and control methods, the corresponding ball valve models are also different. In order to avoid errors in the selection of the user, and to ensure that the pneumatic ball valve can be used normally, more instruments Self-Control Valve Company hereby provides instructions for the preparation of pneumatic ball valve models for everyone to understand and recognize!

Pneumatic ball valve model editing instructions are mainly from the increase of additional conditions of the pneumatic ball valve, the selection of the drive mode, the difference of the connection form, the change of the structure form, the type of sealing material, the level of valve pressure and the material of the valve body, etc. to facilitate the explanation, hope It is helpful to the majority of users.
Pneumatic ball valve model representation method:
