Product Introduction:

An electric butterfly valve typically consists of a quarter-turn electric actuator and a butterfly valve body, mechanically connected and installed to form a complete unit. A 90-degree rotation allows for rapid opening and closing, offering convenient operation and excellent fluid control characteristics. It is especially suitable for installation in pipelines for shut-off, regulation, and water conveyance in various industrial systems such as petroleum, chemical, metallurgy, power plants, municipal water supply, environmental protection, food, papermaking, and environmental facilities.

Product Features:

• Hard alloy overlay on the valve body: The valve body is overlay-welded with hard alloy, ensuring excellent wear resistance and a long service life.
• Stainless steel sealing ring: The sealing ring is made of stainless steel, combining the advantages of both metal and elastic seals.
• Three-dimensional eccentric sealing structure: The flanged electric butterfly valve adopts a three-dimensional eccentric sealing structure, minimizing wear between the seat and the disc during opening and closing, resulting in better sealing performance.
• Large-diameter specifications: The large-diameter specifications adopt a high-strength, high-flow area, and low-flow fine-mesh structure.

Product Structural Features:

• Sealing material selection: Stainless steel and oil-resistant rubber pairs are selected for the sealing materials, ensuring a long service life.
• Butterfly valve disc design: The butterfly valve disc adopts a frame structure, providing high strength, a large flow area, and low flow resistance.
• Rubber sealing ring placement: The rubber sealing ring can be placed on the valve body or the butterfly disc, allowing users to choose based on different media characteristics.
• Double eccentric structure: The flanged electric butterfly valve adopts a double eccentric structure, ensuring increasingly tighter sealing and reliable sealing performance.
