3PC Forged Steel Ball Valve
KOSEN 3PC Forged Steel Floating Ball Valves has a good sealing performance, however, we need to consider whether the outlet side seat could bear the working pressure as the movable ball would nearly pass all the medium pressure to the seat. For this reason, the floating structure is generally for middle & low pressure working pressure.

Cast Trunnion Ball Valve
KOSEN Cast Trunnion Ball Valve have been designed for severe oil and gas applications,including production,transportation and distribution.
KOSEN Cast Trunnion Ball Valve designed the Side-Entry Trunnion-Mounted Ball Valves to assure bi-directional sealing of the valve with two independent floating seats. The design of these seats minimizes the torque required to operate the valve without losing the sealing power. This power is assured by zero differential pressure to the valve's maximum rated pressure. In addition, these repairable valves are manufactured to seal off both seats at the same time and to allow bleeding of the entrapped cavity pressure (DBB) with the ball in the closed position. The DBB feature allows for verifying that the seats are properly sealing.
Full Welded 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.

V Type Ball Valve
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.
