Application

This product is a combination of a butterfly valve with the LDE series electric actuator (available in explosion-proof version), which can be controlled by inputting control signals (4-20mA or 1-5V DC) and a single-phase power supply. The electric butterfly valve has advantages such as strong functionality, compact size, light weight, reliable performance, simple matching, and high flow capacity.

It is particularly suitable for applications involving viscous, granular, and fibrous media. Currently, this electric control valve butterfly valve is widely used in industrial automatic control systems across various industries, including food, environmental protection, light industry, petroleum, papermaking, teaching and research equipment, and power.

Product Features

  • Three-dimensional eccentric structure for minimal wear and excellent sealing

  • Multiple sealing options including multi-layer sealing, hard sealing, and metal sealing

  • Capable of withstanding high temperatures, high pressures, and corrosion.
