Cast Floating 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.

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.

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.

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.
