Forged Floating 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.

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.

KOSEN Cast Floating Ball Valves are designed manufactured to provide maximum service life and dependability. All ball valves are full ported and meet the design requirements of American Petroleum Institute Standard API 608&API 6D British standard BS5351 and generally conform to American Society of Mechanical engineers standard ASME B16.34 valves are available in a complete range of bady/bonnet materials and trims.

The three - way ball valve can be divided into L type and T type. The L type three way ball valve is used to switch the medium flow direction, so that the two vertical channels can be connected. The three way ball valve usually adopts the two seat structure, and it can also adopt four seat structure according to the user's request. The four valve seat sealing three ball valve has beautiful shape and compact structure. It can not only switch the flow direction of the medium, but also make the three channels interconnected. At the same time, it can close any channel, make the other two channels connected, and flexibly control the flow or shunt of the medium in the pipeline.
