1、 Overview of ZARD Electric Regulating Butterfly Valve

ZARDElectric regulating butterfly valveAdopting intelligent control, electric or pneumatic actuators can be used to adjust parameters such as pressure, flow rate, temperature, and liquid level. It has the advantages of compact structure, strong functionality, small size, good sealing, reliable performance, simple matching, and large flow capacity, especially suitable for occasions where the medium is viscous, contains particles, or fibers. At present, this valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.
