Product Details

Butt welding gate valve is divided into integral type (one piece), two pieces and three pieces. Valve body casting adopts advanced technology, reasonable structure and beautiful shape. The valve seat adopts elastic sealing structure, reliable sealing and easy opening and closing; the valve rod adopts the bottom mounting structure with back sealing, and when the valve chamber is abnormally pressurized, the valve rod will not be rushed out. The pneumatic two-piece and three-piece ball valves are connected by BW socket welding (SW), and can be equipped with international standard ISO bracket platform and locking device. The three piece ball valve is small in volume and consists of three parts of valve shell. It is formed by clamping the middle valve body and valve ball from both ends with four long bolts. The utility model has the advantages that the pipeline thread is not disassembled during the maintenance and disassembly, and the four bolts are directly disassembled, and the middle part of the valve body can be taken out. It is suitable for light industrial machinery with small volume and narrow space. Pneumatic ball valve with small size, simple matching, large circulation capacity, especially suitable for the medium is viscous, containing particles, fiber properties occasions. At present, the valve is widely used in the industrial automatic control system of food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and scientific research equipment, electric power and other industries.

Product characteristics
