The electric ball valve has a simple structure, consisting of only a few parts, and saves material consumption; it is small in size, light in weight, small in installation size, and has a small driving torque. It is a pressure regulating valve that is easy and quick to operate and can be quickly opened and closed by rotating 90°. It also has good flow regulation function and closed sealing characteristics. In the application range of large and medium calibers, medium and low pressures, the electric ball valve is the dominant valve form.
① Integral valve body
The integral valve body without any pipe joints is not affected by the stress of pipes or bolts, and since the valve body has no pipe joints, the pressure-resistant shell will not be affected by the "sudden change" of pressure
② V-port valve body
The electric ball valve has a V-port valve body, which can ensure the accuracy of control within the entire range even in the case of small flow or high viscosity media
③ O-type sealing ring
The leak-proof and durable valve seat of the electric ball valve is lined with a PTFE cup or O-type sealing ring with a stainless steel inner core on its outer diameter. The valve seat is made of tungsten-cobalt hard alloy with a larger cross-section, and the structure of the valve seat is further strengthened by an alloy corrugated spring
④ V-port notch
When the electric ball valve is closed, a wedge-shaped shearing effect is generated between the V-port notch and the electric ball valve seat, which has both self-cleaning function and can prevent the ball core from getting stuck. The electric ball valve is particularly suitable for pipelines with scale freezing or containing fibers and granular solids.
