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.

Forged Trunnion 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.
Two Piece Ball Valve
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.Learn More
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.
Floating DBB Ball Valve
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.Learn More
