Segment ball valve description
Segment ball valve is a rotary shutoff valve with V- shaped gap in the core. Using it with valve positioner may realize ratio adjustment. It is widely used in industrial sectors such as petroleum, chemical, paper-making, metallurgy water treatment, and so on. It may regulate or cut off the media in pipeline. It has a big flow coefficient, booster ring at valve seat for adjusting sealing force load, so that can ensure tight seal.
Product features of segment ball valve
A. Movable spring -loaded valve seat structure prevents jamming or severing between ball core and valve seat to make the seal reliable and useful life long .
B. There is shearing action between V- shaped notch ball core and metal valve seat, so it is especially applicable to media containing fiber. micro solid materials, pulp, and so on.
C . When it is fully open, there will be a big flow capacity and small pressure loss and the medium will not deposit in the valve cavity.
D.The valve has precise adjustment and reliable position function. The flow characteristic is approximate equal percentage and the adjustable range is wide with largest adjustable ratio of 100: 1.
