Pneumatic ball valves have the advantages of rapid cutoff, low fluid resistance, simple structure, easy maintenance and so on. Its main function is to control the flow of fluid medium, and can cut off, distribute and change the direction of flow of the medium in the pipeline.
Pneumatic ball valve introduction
Pneumatic ball valve is a ball valve with a pneumatic actuator. This actuator switching speed is very fast, the fastest only 0.05 seconds once. Usually, pneumatic ball valves are equipped with various accessories, such as solenoid valves, air source processing triplex, limit switches, positioners and control boxes. The function of these accessories is to realize local control and remote centralized control. By operating in the control room, the valve can be easily controlled, without the need to visit the scene or risk high altitude, thus saving human resources, time and improving safety.
Function and working principle of pneumatic ball valve
Pneumatic ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. The working principle of pneumatic ball valves is to rely on the rotation of the spool to make the valve open or occluded. Pneumatic ball valve switch light, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance. The sealing surface and the ball surface is often in the closed state, is not easy to be media erosion, in various industries are widely used.
Pneumatic ball valve application
- Chemical industry: Pneumatic ball valves can be used in the chemical industry for a variety of acids, alkalis, salts and other corrosive media flow control and regulation, can withstand high temperatures and high pressures and other harsh conditions, applicable to all aspects of chemical production.
- Petroleum field: It is used for pipeline control of oil, gas and water in the process of petroleum mining, conveying and processing, which can withstand the harsh working environment, and can respond quickly and realize accurate control.
- Metallurgical field: Used in the metallurgical industry for high temperature, high pressure gas and liquid media flow regulation and control, can accurately control the flow, so as to ensure the quality of metallurgical production process.
- Electric power field: Used in thermal power generation, nuclear power and other fields for water, steam, gas and other media flow regulation and control, can withstand high temperatures and high pressures and other harsh conditions, with high reliability and high precision.
- Food field: In the food, pharmaceutical and other fields for food, medicine and other media flow control and regulation, can prevent pollution and impurities, in line with health requirements.
