Application Areas
This product is equipped with a butterfly valve and an LDE series electric actuator (optional explosion-proof), which can be controlled by inputting control signals (4-20mA or 1-5~VDC) and single-phase power supply. The electric butterfly valve has the advantages of strong functionality, small size, lightweight, reliable performance, simple matching, and large circulation capacity. It is particularly suitable for applications where the medium is viscous, contains particles, and has fibrous properties. At present, this electric regulating valve butterfly valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, teaching and research equipment, and power.
