Electromagnetic Butterfly Valve - Product Overview
Electrical Wafer Butterfly Valves are composed of a high-precision electric actuator and a wafer butterfly valve. The actuator features an integrated structure, with switching models accepting AC220V input voltage and providing a passive contact signal (or switch-in-position light signal) output. Adjusting models require control signals (DC4-20mA or DC1-5V) and a single-phase power supply to operate. These electric wafer butterfly valves are characterized by strong functionality, compact size, affordability, reliable performance, simple matching, and high flow capacity. They are particularly suitable for applications involving viscous media, particles, and fibrous materials. Electric wafer butterfly valves are widely applicable in industrial process automatic control systems across various industries such as food, environmental protection, light industry, petrochemicals, educational equipment, papermaking, and electricity.
