Thread Ball Valve

Thread Ball Valve and the flange gate valve are the same type of valve. The difference between its closure is a sphere, and the center line of the sphere around the valve body is rotated to achieve a valve that is opened and closed. The ball valve is mainly used in the pipeline to do the flow direction of cutting, allocation, and changing the medium. Two -piece ball valve, three -piece ball valve, is a new type of valve that has been widely used in recent years. The thread ball valve has the following advantages editing broadcast 1. The fluid resistance is small, and its resistance coefficients are equal to the same length. 2. Simple structure, small volume, light weight. 3. Tightly and reliable, the sealing materials of the ball valve are widely used in plastic and sealing, and have been widely used in vacuum systems. 4. It is easy to operate and quickly and close. From full opening to full level, it only needs to rotate 90 ° to facilitate long -distance control. 5. Convenient maintenance, simple ball valve structure, sealing ring is generally active, and it is more convenient for disassembly and replacement. 6. When open or full -closed, the seal of the sphere and the valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve density cover. 7. The scope of application is wide, from small to a few mm to a few meters, from high vacuum to high pressure.

Size: 1/2"-2".
According to NTC3538:2009 Standard.
Female/male threads.
Aluminum handle.
