Product Information

Flange ball valve is a commonly used switch regulating valve, with simple structure, easy operation, reliable sealing, small flow loss and other advantages, widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical, food and other industries. It is mainly composed of valve body, valve stem, valve seat, valve flap, valve cover, valve spool, valve shaft, valve seat gasket, valve stem gasket, valve stem handle and so on. Flange ball valve through the flange connection to fix the connection between the valve and the pipeline, the flange connection can be threaded flange, butt welding flange, nut flange and other different types, with strong connecting force and sealing. The working principle of flange ball valve is that the opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the valve stem to achieve opening or closing by rotating 90°, so as to achieve the purpose of regulating the flow.

Product Advantage

1, Small fluid resistance: the resistance coefficient of the flange ball valve is equal to that of the same length of pipe section, which means that it will not add additional fluid resistance in the pipeline, which is conducive to maintaining the efficiency of the fluid.
2, Simple structure, small size, light weight: flanged ball valves have a simple design, which makes them take up little space, easy to install and transport, and also reduces the overall weight.
3, Tight and reliable: the sealing surface material of the ball valve is widely used in plastic, which has good sealing properties and can maintain efficient sealing performance even in the vacuum system.
4, Easy to operate: flange ball valve opening and closing operation is very fast, from fully open to fully closed only need to rotate 90 °, very suitable for remote control operation.
Convenient maintenance: the structural design of the ball valve makes maintenance and repair easy, and the seal ring can be easily disassembled and replaced.
5, A wide range of applications: flange ball valve diameter can be from a few millimetres to several meters, suitable for a variety of working conditions from high vacuum to high pressure.
