Pneumatic flange ball valve adopts advanced casting technology, with reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which ensures reliable sealing and easy opening and closing. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally pressurized, the valve stem will not be flushed out. Pneumatic ball valve (small) can be matched with pneumatic actuators, solenoid valves, limit switches, and air filter pressure reducing valves. The input, power supply and air source can control the operation and realize the switching of fluids. . It is powered by compressed air, and the valve stem drives the valve core to rotate in the valve body, which can achieve full opening and full closing. It has the characteristics of compact structure, small size, reliable operation, good sealing, easy maintenance, convenient installation and strong adaptability. It can be widely used in industrial automatic control systems such as petroleum, chemical industry, heating network, light industry, tap water, high-pressure equipment, pharmaceuticals, biology, etc. for remote centralized control or local control.
