The main features of a V-ball, compact Shandong valves, small size, can erect advantage lying installation. 2, with excellent regulation characteristics: V-type valve has an approximately equal percentage inherent flow characteristics and up to 300: 1 turndown. So V-ball can provide precise control over a wide amplitude range. Pneumatic V-ball is suitable for two off, adjust the occasion V-ball processors, 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.
