■ Overview

ZDRW electric triple eccentric butterfly valve consists of an electronic electric actuator and a triple eccentric butterfly valve.

The latest three eccentric design principle has the characteristics of good sealing performance, smooth valve body flow channel, large flow capacity, low friction between the butterfly plate and valve seat, long service life, wide applicability, and easy maintenance.

Widely used in industries such as petroleum, chemical, power, metallurgy, steel, papermaking, pharmaceuticals, food, textiles, and light industry.
