The pneumatic ball valve is a combination of a pneumatic actuator and valve. It is widely used in many industries because of its convenient operation and no need to go to dangerous workplaces. The pneumatic actuator runs fast, and the switching speed can reach 0.05 seconds/times, so it is commonly known as a pneumatic quick cut-off ball valve. Pneumatic ball valves are usually equipped with various accessories such as solenoid valves, air heat source treatment triples, limit switches, positioners and control boxes for local and remote centralized control. The valve of actuator operated ball valve can be controlled in the control room. It saves a lot of human resources, time and safety because you don't have to go to the site or high places, and you don't have to do dangerous manual controls.
The main features of the pneumatic ball valve are compact structure, convenient operation and maintenance, suitable for general working media such as water, solvent, acid, natural gas and harsh working media such as oxygen, hydrogen peroxide, methane and ethylene. The valve body of the pneumatic ball valve can be one-piece or combined.
Selection of pneumatic ball valve:
The properties of the medium need to be considered. Many chemical media are corrosive and grainy, which is easy to damage the sealing surface. How to solve the problem of the pneumatic ball valve can choose a corrosion-resistant fluorine-lined material for wear-resistant treatment, so that there is a pneumatic fluorine-lined ball valve. Wait.
The ball valve material can be selected according to the on-site working conditions. Generally, there are ductile iron, stainless steel, cast steel, carbon steel, plastic, etc. According to the requirements of higher quality, there are also sanitary pneumatic ball valves with better materials.
It means working pressure, which can be divided into low pressure, normal pressure, medium pressure, high pressure, 1.6MPa is a common pressure, of course, this is also used as a reference for selection data.
These industrial valves types can be divided into a high-temperature pneumatic ball valve, low-temperature pneumatic ball valve, medium temperature pneumatic ball valve and normal temperature pneumatic ball valve.
According to the ball valve channel position
It is divided into a three-way pneumatic ball valve and a teaching pneumatic ball valve. According to the characteristics of the ball valve, it is divided into a floating ball valve and fixed ball valve, etc. In short, different types should be selected according to actual working conditions.
