5. Selection of pneumatic ball valve is more critical than calculation
Calculation and selection are relatively more critical and complicated. Since the calculation is only a simple formula, it does not depend on the accuracy of the formula calculation, but depends on whether the main parameters of the given processing technology are accurate. Model selection involves a lot of content, and a little carelessness will lead to poor model selection, which not only leads to waste of human resources, human and material resources, and capital, but also the actual application effect is not ideal, resulting in many application problems, such as credibility, service life, operation quality, etc.

Which kinds and characteristics of pneumatic butterfly valve
Shanghai Songxia Shock Absorber Co., Ltd. has already prepared enough supplies when the peak season is coming. Recently, many customers have inquired about pneumatic butterfly valves. As a commonly used pipe hose, pneumatic butterfly valves have a large sales volume when the pipe fitting peak season comes. Pneumatic butterfly valves are widely used in modern industry and are an important part of modern industry. Pneumatic butterfly valve is a kind of hose which is very common among them. It is mainly used as communication wire and cable maintenance pipe and civil shower hose. What are the classifications of pneumatic butterfly valves? Now let's understand the classification of pneumatic butterfly valves and the characteristics of pneumatic butterfly valves.
1、 What are the classifications of pneumatic butterfly valves
1. Threading pneumatic butterfly valve: the threading pneumatic butterfly valve is mainly made of stainless steel, which has excellent flexibility, corrosion resistance and tensile strength, high temperature resistance and wear resistance, and is mainly used as the maintenance pipe of wires and cables.
2. Corrugated pneumatic butterfly valve: Corrugated pneumatic butterfly valve is mainly composed of bellows, mesh sleeve and joint. Bellows play a flexible role in corrugated pneumatic butterfly valves, and are made of thin-walled stainless steel with spiral or annular waveforms. The mesh sleeve is woven by inserting metal wires or metal belts in a certain order. It is installed on the outer surface of the metal bellows and has the function of reinforcement and shielding. The construction of joints can be roughly divided into three categories: screw type, flange type and quick type. For different application requirements, the connection modes among bellows, mesh sleeve and joint include welding type, mechanical clamping type and hybrid type.
3. Plastic coated pneumatic butterfly valve: plastic coated pneumatic butterfly valve is a new type of hose. Its inner layer uses stainless steel hose or galvanized hose for special disposal, and its outer layer uses PVC raw materials, which has the characteristics of ultraviolet resistance and anti-aging.
Shanghai Zhuangji Pneumatic Butterfly Valve Manufacturing Co., Ltd. has many years of experience and skills, and has a large number of customer support around the world. As a commonly used pipe fitting, pneumatic butterfly valves sell well at home and abroad. Welcome new and old customers to visit the factory and purchase.
