Electric Regulating Butterfly Valve for Air & Dust Gas

I. Overview

Electric butterfly valves, utilized in conjunction with electric actuators, are widely applied across various industrial sectors, including metallurgy, electric power, petroleum, chemical engineering, and building materials. By adjusting the flow rate of pipeline media—such as liquids, gases, and steam—in response to varying control signals, these valves facilitate the automated regulation and remote control of industrial production processes.

II. Working Principle

The electric actuator rotates the valve plate to adjust opening angle (0°–60°/80°), so as to control air flow or gas flow.

III. Features & Advantages

1. Electric Automatic Adjustment: 0–10mA / 4–20mA signal control.
2. Wide Temperature Range: Normal temperature: -15°C to 250°C; Medium temperature: -40°C to 450°C.
3. Excellent Sealing Performance: Minimal leakage and stable operation.
4. Flexible Installation: Flange connection for easy installation and maintenance.
5. Wide Caliber Range: DN50 to DN3000 mm.

IV. Application

• Metallurgy, power plant, cement plant
