Pneumatic ball valve features: 1, pneumatic ball valve is a new generation of ultra-short flange away from the ball valve, the ball channel shape of a rectangular, V-shaped and O-shaped. The series of products have the advantages of compact structure, small size, light weight, convenient installation and the like, and can be widely used in the fields of petroleum, chemical industry, metallurgy, power station, light industry, etc. to automatically adjust the oil, water, gas and pulp or fibrous fluid Or cut off the control. 2, Pneumatic ball valve pneumatic dual-piston rack and pinion actuator and ultra-short flange from the ball valve combination, the valve body part with the same electric ball valve, pneumatic piston actuator is divided into two kinds of spring-type and spring-free. Failure under the requirements of the valve fully open or closed with a spring-loaded (by the spring recovery tension reset), the fault requires security, with no spring. It mainly consists of cylinder, spring, piston, piston rod, front and rear cylinder head, rack, output shaft and other components. On the two on-off valve, solenoid valve to be equipped with travel switches, etc .; contrast type control valve, with locator. 3, the valve body with a one-piece structure. Through precise machining and assembly, the ball core is loaded from one end, and then the pressure ring is screwed, so that the two soft-sealed valve seats and the core keep good contact and sealing. At the same time, the pressure ring within the mat also achieve a good seal, so that the leakage of the valve work is zero. As a result of the overall structure of the valve body, so the valve to achieve ultra-short flange distance, the whole weight is greatly reduced, only about 50% of similar ordinary ball valve.
