Product Overview
The electric V-port ball valve features a V-shaped ball core, enabling linear regulation with a large adjustable range. When the valve is closed, a wedge-shaped shearing action is generated between the V-notch and the valve seat. This not only provides a self-cleaning function but also prevents the ball core from getting stuck, making it particularly suitable for pipelines prone to scaling and freezing. It is ideal for controlling media such as pulp, sewage, suspended media containing fibers and solid particles, as well as powder and granular media.
