■ Overview
The ZDRV electric V-shaped ball valve consists of an electronic electric actuator and a V-shaped ball valve. It is a type of angle stroke regulating valve that controls fluid flow by rotating a V-shaped notched spherical valve plate against the sealing surface within a small opening range.
The V-shaped notch ball panel not only increases the adjustment ratio, but also has a shear effect on the sealing ring during flow interception, making it suitable for control systems that require a large adjustment ratio, as well as for controlling fluids containing fibers and slurries.
Widely used in industries such as petroleum, chemical, power, metallurgy, steel, papermaking, pharmaceuticals, food, textiles, and light industry.
