Generally, the operator is not familiar with the control system and manual operation system of the pneumatic butterfly valve, so the pneumatic butterfly valve will be damaged due to improper operation during the operation. Therefore, the operators who operate the pneumatic butterfly valve and other related valves need professional personnel for training, In order to prevent improper operation during the whole construction process, which may damage the product equipment, cause material omission or material damage, and finally bring some property losses to the enterprise and the country.

Do you know the characteristics of pneumatic butterfly valve materials
Joint at both ends of pneumatic butterfly valve: the joint mainly includes thread joint, flange joint and quick joint joint. The three major influences of pneumatic butterfly valve: reduce the installation stress of the pipeline, compensate for the movement of the rated position of the pipeline, and experience the vibration of the pipeline system.
The stainless steel mesh sleeve is the main pressure bearing part of the metal braided hose installed in the pressure pipeline. At the same time, it protects and impregnates the pneumatic butterfly valve. According to the size of the pressure in the pipeline and the application site, one or more layers of stainless steel wires or steel strips can be selected to stop being woven according to certain parameters to form a high-pressure pneumatic butterfly valve, The pressure range of the metal braided hose produced by our company is generally PN0.6-32.0MPa, up to 42.0MPa. Stainless steel mesh cover mainly includes steel mesh cover and steel mesh cover.
Features of corrugated pneumatic butterfly valve:
1. Maximum allowable shrinkage per wave recommended: full height △ α= ± 24mm half height △ α= ±12mm。
2. Ash baffle: it can not be used for air duct or pipe with little dust, and it should be used for flue with much dust.
3. In order to reduce the number of corrugated sections of bellows, 50% cold drawing shall be considered.
4. The standard half height corrugated pneumatic butterfly valve is applicable to places with a sectional area of less than 4.6 square meters and the overall dimensions of the flue and air duct where one side is less than 1.5 m but more than 0.6 mm. Full height corrugated pneumatic butterfly valve is applicable to all flue ducts.
The corrugated pneumatic butterfly valve has excellent flexibility, fatigue resistance, high pressure resistance, bump temperature resistance, corrosion resistance and many other characteristics. Compared with other hoses (rubber and plastic hoses), its service life is much longer, so it has higher comprehensive economic benefits. With the growth of modern industry, your demand for high temperature and high pressure resistant corrugated hoses is growing.
Scope of hose sharing: flexible walk pipes are required to be filled to prevent vibration, and pipes are used for steam, gas, air, heavy oil, petroleum, chemicals, etc.
