SKSPO top-mounted eccentric half ball valve

structure and use

1, the pressure loss is small: when the full water loss is zero, the flow channel is completely smooth, and the medium will not be deposited in the valve body cavity;
2, resistant to wear: V-shaped opening of the ball cap and metal valve seat between the shear, in the closing process, only at the last moment of the ball cap to seat, does not form friction, and the valve seat made of wear-resistant nickel alloy, not easy to be scour wear, so suitable for containing fiber, small solid particles, pulp, etc;
3. Suitable for high flow rate medium: straight-through flow channel, solid eccentric crankshaft makes it suitable for high flow rate without vibration;
4, long life: no vulnerable parts, due to the eccentric effect, the valve opening and closing when the sealing surface without friction, the service life is long;
5, easy maintenance: the valve maintenance does not need to be removed from the pipeline, as long as the valve cover can be repaired;
6, widely used in water, sewage, containing small solid particles, water, steam, gas, natural gas, oil and so on.
