Electric Wafer Ball Valve

Electric wafer ball valve is the execution unit in the electric unit combination instruments.Wafer ball valve with electric actuator can achieve proportional control and receive on/off or 4-20mAC or 1-5VDC signals for proportional action.The valve ball has a v-shaped slit, which is rotated relative to the hard seal valve to generate shearing force, which can cut the fiber and prevent jamming.Electric wafer ball valve is especially suitable for the regulation of mud and fibrous medium, as well as medium containing fine solid suspensions.

The excellent adjustment performance of the electric v-notch ball valve makes the product widely used in high-precision control of various industrial fields such as petrochemical, fine chemical, paper-making, metallurgy, waste water treatment, boiler feed water. It realizes medium flow regulation and cut-off in the pipeline.

The Features of V-notch Electric Actuator Wafer Ball Valve:

1. Adopting ultra-short flange distance structure, the valve seat is close to the end face flange, so the material retention is less, and the sealing performance is superior. Compared with ordinary electric ball valves, the weight is greatly reduced, which is about 50% of that of ordinary electric ball valves. It has compact structure and small size.
2. The valve disc determines the characteristics of the valve.And the unique v-notch ball structure improves the control stability of the conventional ball valve. The flow rate is precisely controlled by the opening in the V-shaped notch of the valve ball.
3. The V-shaped notch formed between the valve seat and the valve ball can easily cut off various impurities in the pipeline and effectively ensure the smooth flow of the pipeline.
4. V-port angle of electric wafer ball valve can be customized to meet more accurate shut-off characteristics and control functions.
