Forged Trunnion Ball Valve

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.

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.

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.

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.
