1. PVC compact ball valve function: the basic function of ball valve is to manually control the water flow switch. The link is made so that it can be disassembled later.
2. PVC compact ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small torque can close tight.
3. PVC compact ball valve is most suitable for switch, cut off valve use, V-type ball valve. In addition to the pipe parameters, special attention should be paid to the environmental conditions of the use of the electric valve. Because the electric device in the electric valve is a mechanical and electrical equipment, its use state is greatly affected by its use environment.
4. PVC compact ball valve came out in the 1950s, with the rapid development of science and technology, production technology and product structure of continuous improvement, in just 40 years, has rapidly developed into a major type of valve. In western industrial developed countries, the use of ball valves is rising year by year.
5. In China, PVC compact ball valve is widely used in petroleum refining, long-distance pipeline, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, plays a pivotal role in the national economy. It has a 90 degree rotation action, the cock body is a sphere, a circular through hole or channel through its axis.
