1.Electric wafer butterfly valve Product Overview

Electric wafer butterfly valve is composed of high precision electric actuator and wafer type butterfly valve, actuator with integrated structure, switch input voltage AC220V, output passive contact signal (or switch position signal), adjustable input (DC4-20mA or DC1-5V) control signal and single-phase power can control the operation, electric butterfly valve has strong function, small volume, light and pleasant, reliable performance, simple matching, large flow capacity, particularly suitable for medium thick, containing particles, fiber nature of the occasion. Electric butterfly valve can be widely applied to the process of food industry, environmental protection, light industry, petroleum, chemical industry, papermaking, teaching equipment, electric power and other industries in the automatic control system.
