3PC Forged Steel Ball Valve

Fully Welded Ball Valves are especially designed for gas transportation and storage industries. The fully welded body design can prevent any potential external leakage from connection of body and bonnet. In addition, the forged body with the advantages of consistent grain size and even thickness. Thus it inherently eliminates the conventional casted valve material defects, such as: shrinkage, porosity. The fully-welded ball valve adopts forged material, welded body, instead of bolts and nuts, to aviod any potential leakage from body.The forged body with regular structure and even thickness can avoid shrinkage cavities, pin holes, cracks, sand holes and other defects occurring to casting body valves.Fully-welded ball valves can be spherical and cylindrical type. Usually the spherical type has only one welding seam on the body, the cylindrical type has two welding seam on the body.

Female threaded ball valves are suitable for using on pipelines of medium or low pressure to turn off or swith on pipeline medium. Operation manners are in general of manual, and pneumatic or electric actuators are available.Based on design structures, the valves get divided into three pieces, two pieces, and one piece types. Female Threaded ball valve & butt welded ball valve could be divided into one piece, two piece and three piece body. Advanced casting technology is used for body with reasonable structure and beautiful appearance. Elastic seat material is adopted to ensure reliable sealing together with easy operation.

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.
