The three-piece ball valve connection is also butt welded (BW) socket welded (SW), and can be equipped with international standard ISO support platform and locking device. The three-piece ball valve is small in size and consists of three parts of the valve shell, which is formed by clamping the middle valve body and the valve ball from both ends through four longer bolts. Its advantage is that the maintenance disassembly does not need to remove the pipe thread, directly remove the four bolts, the middle part of the valve body can be taken out. It is suitable for small volume and narrow space of light industrial machinery. It has a small volume and simple supporting, large circulation capacity, especially suitable for the occasion where the medium is viscous, containing particles and fiber properties. At present, the valve is widely used in the industrial automatic control system of food, environmental protection, light industry, petroleum, paper making, chemical industry, teaching and scientific research equipment, electric power and other industries.
