Cast Floating Ball Valve

The pneumatic ball valve is a pneumatic actuator with a ball valve. Pneumatic actuators perform relatively fast, and the fastest switching speed is 0.05 seconds / times, so it is usually called pneumatic quick shut-off of ball valves. The pneumatic ball valve is usually equipped with various accessories such as the solenoid valve, the gas source treatment triad, the limit switch, the locator, the control box, etc. to achieve local control and long distance centralized control. In the control room, the valve switch can be controlled. It does not need to run to the scene or at the high altitude and the dangerous zone. It saves human resources, time and safety.

The wafer ball valve has the features of compact structure, light weight, simple installation, easy operation and so on. Generally this valve is manual operated, while worm gear, pneumatic or electric actuation is optional when needed.Floating Ball Valves made by Chaoda are suitable for use on various kinds of pipelines from Class 150 to Class 300 to turn on or cut off the medium flowing in pipeline.

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.

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.
