V-ball (pneumatic control) is a quarter-turn valve V-type structure, it positioner supporting the use of proportional control can be achieved; V-type valve (pneumatic control) valve is ideal for a variety of occasions to adjust V-ball manufacturing providers, with a rated flow coefficient, adjustable ratio, good sealing effect, adjust the zero-sensitive performance V-ball vendors, small size, can be installed vertical lying. Suitable for controlling gases, vapors, liquids and other media. Pneumatic V-ball is suitable for two off, adjust the occasion, can be equipped with a valve positioner input control signal (4-20mADC or 1-5VDC) gas source to control operation. Also with the travel limit switches, solenoid valves, FRL and 0.4-0.7MPa gas source switching operation can be realized, and sent two pairs of passive contact signal indicating the switching valve pneumatic V type ball valve with a simple connection, compact , small size, light weight, low resistance, stable and reliable operation. Pneumatic V-ball is widely used in petroleum, chemical, power, metallurgy, steel, paper, pharmaceutical, food, textile, light industry and other industries.
