Threaded Ball Valve

Ball thread ball valve (ball valve) is a closing piece is a ball, the ball around the center line of the valve body for rotation to open, close a valve. Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium. Two-piece ball valve, three-piece ball valve, is a new type of valve widely used in recent years, the valve is generally installed horizontally. Screw ball valve is a kind of ball valve, and the connection form of pipe is threaded connection, in addition to flange ball valve, welding ball valve and so on.

 

The threaded ball valve is a closed ball that is opened and closed by rotating the center line of the valve. Valves are mainly used to cut off, distribute and change the flow of media on the pipeline. Two piece ball valve, three piece ball valve is widely used in recent years. The valve is usually mounted horizontally. Screw ball valve is a kind of ball valve, and the connection form of the pipe is screw connection, and flange ball valve, welding ball valve, etc. Screw ball valves can also be divided into internal screw ball valves and external screw ball valves. Screw ball valve is suitable for nominal pressure PN 16~140, nominal size DN 8~50 low pressure, small diameter pipeline, used to cut off water flow and change the distribution of water flow or for quick opening and closing places. Main features: 1, flow resistance is small; 2. Simple structure; 3, small volume, light weight; 4, ball valve sealing surface material selection of plastic, good sealing; 5, easy to operate, open and close quickly, easy to remote control; 6, easy maintenance, sealing ring is generally active, easy to disassemble and replace; 7, fully open or fully closed, ball and seat sealing surface and medium isolation, medium through the valve sealing surface will not cause erosion.

 

 

Threaded ball valve locking mechanism on handle is to lock the handle when the valve is in open position or close position.

 

Reduced bore type ball valve where the bore size is smaller than the internal diameter of pipework which it installed on. It is available in stainless steel SS316 material and come with PTFE seat. It is made in one body part which lead to cost effective and reduce leakage paths.

• Controls the flow of liquids and/or gasses
• Temperature range is minus 40 to 400°F
• A fluorocarbon elastomer stem O-ring prevents stem leaks.
