1. Preeminent performance of adjustment control
The ball is of "V" pattern. At any position from full open to full close, it always keeps the standard geometry. The large adjustable extent is from 100:1 to 200:1, the CV curve of discharge characteristic is similar to the percentage curve, which may realize the precise control of the flow.
2. One piece body
One piece integral body, the strength is high, stress deformation resistance is strong, has no central flange, confinement reliability is improved, has no bending transition at the flow passage, not accumulate, not block, has little influence upon the fluid.
3. Reliable seat sealing
The sealing surface build-up welding is handled by hard facing and employ the advanced seat grinding technology and griding ball technology to make V type ball valve have reliable sealing performance which can achieve the "V" sealing grade of ANSI B16.104 specified. The special requirement can achieve VI grade.
4. Ball
The ball hard surface handled by STL, tungsten, etc. Both the two ends are V pattern, which is easy to precise control for flow also can realize the shearing action for the fluid containing cellulosic, the high-viscosity fluid containing solid particles when shutting.
