Three Piece Ball Valve
Female threaded ball valve is a device to cut off or connect the flowing medium with a rotated ball as the closure member. Two or three piece ball valve is a newly widely used valve with generally horizontal installation. Extended bonnet could be designed according to client's need. And the thread of valve's two ends could be manufactured as to both GB and ANSI standard. The stem of female threaded ball valve has the anti blowing out structure which prevents the blowing out of stem under unnormal pressure in valve cavity. BW&SW connection could be chosen for 2&3 piece body and ISO mounting pad or locking device are available if needed.Learn More
Electric Actuator Ball Valve
KOSEN series electric actuator is used for controlling valves of 0-270 Degree rotation and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc.. It is widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It can be drived by 380V/220V/110V AC power or 24V/110V DC power. Control signal can be 4-20mA current signal or 0-10V voltage signal. It can move the valve to desired position, realize automatic control. The maximum output torque is up to 2000N·m.
Cast Floating Ball Valve
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.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.
