Cast Iron Ball Valve

Ball valves (Flanged general and butt-welding connection optional) are suitable for using on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN160 to cut off or allow the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs.
Ball valve is used to cut off, distribute or change the flowing direction of medium. 90°'s turning with very small torque could seal the valve very well.

V type ball valve is suitable for using on various kinds of pipelines of Class150~Class300, and PN16~PN40. There are two kinds of applications for V type ball valve according to customers' different requirement. One is used for cutting off or switching on the pipeline medium. The other is used as control valve for regulating the medium fow capacity in pipelines. Operation manners for cutting off Flanged V Type Ball Valve include manual, worm gear, pneumatic or electric actuators, where as for regulating type V type ball valve, operation manners are of pneumatic and electric actuators.

Female threaded ball valve is a valve with 90°'s rotation to realize opening&closing which is widely used during last few years. Soft sealing electric female threaded ball valve is used in occation needing tight sealing, while metal to metal sealing electirc female threaded ball valve is chosen for high temperature or corrosive serving condition. Trunnion electric female threaded ball valve is suitable for big Nominal size or big pressure difference condition. The flowing characteristic of O type electric female threaded ball valve is linear while equal percentage characteristic for V type electric ball valve and eccentric valve, and these two types of valves could be used as regulating purpose.

The DBB double ball valve is designed to replace the complicated connection of multiple valves in the traditional pipeline. Reduce the leakage point in the system, quickly achieve emissions and shut down function. The DBB double ball valve saves the installation space limit. The installation program is simplified. Reduce the pressure of the pipe system. It is convenient to clean and maintain the instrument and reduce the cost. DBB double ball valve has two series of full diameter and reduced diameter. The inside diameter of the full diameter ball valve is in line with the inner diameter of the pipeline, not only with small fluid resistance, but also convenient for pipeline cleaning. The fluid resistance of the shrink ball valve is much lower than that of the same caliber cut-off valve. The weight of the ball valve is about 30% lighter than that of the same caliber ball valve, which effectively reduces the cost and price of production, thus it has been widely used.
