Ear-type Manual Butterfly Valve

The ear-type butterfly valve is a common industrial valve primarily used in pipeline systems to control the flow and direction of fluids. It features a unique ear-type design, secured between pipeline flanges with bolts to ensure a stable connection and excellent sealing performance. Its compact structure and lightweight design make it easy to install and maintain, suitable for various media including water, steam, gas, and corrosive liquids.

The closing component of this type of butterfly valve is a circular butterfly plate, which rotates within the valve body via a rotating shaft to achieve opening and closing operations. When the butterfly plate is parallel to the fluid flow direction, the valve is fully open; when perpendicular, it is fully closed. Ear-type butterfly valves are typically equipped with manual, electric, or pneumatic actuators to meet automation requirements in different scenarios.

Due to its excellent sealing performance and durability, the ear-type butterfly valve is widely used in industries such as petroleum, chemicals, power, metallurgy, and municipal engineering, particularly in environments requiring frequent operation or rapid shutdown. Additionally, its material selection is flexible, allowing for the use of carbon steel, stainless steel, or other special alloy materials based on specific operating conditions, further enhancing adaptability.
