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.

Cast Bronze Ball Valve
Ball valves are mainly used to cut or connect medium in the pipeline, and can also be used to regulate and control the fluid. The hard sealed V ball valve has a strong shear force between the V core and the metal valve seat of the hardfacing hard alloy. It is especially suitable for the medium containing fiber and small solid material. The multi - ball valve can not only flexibly control the switching of the flow, shunt and flow of the medium, but also close any channel and connect the other two channels. This type of ball valves should be installed horizontally in pipes.

One Piece Ball Valve
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.

Mounting Pad Ball Valve
Mounting Pad Ball Valve s rely on rotary valves to make the valves unblocked or blocked. Ball valve switch light, small size, can make large caliber, reliable seal, simple structure, easy maintenance, sealing surface and spherical surface often closed state, not easy to be eroded by medium, widely used in various industries. The Mounting Pad Ball Valves is mainly used for cutting, distributing and changing the direction of flow in the pipeline. Ball valve is a new type of valve widely used in recent years.

Forged Floating Ball Valve
Floating Ball Valves (Flanged general and butt-welding connection is optional) are suitable for using on various kinds of pipeline from pressure Class 150 to Class 1500, PN16 to PN100 to cut off or connect 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.
