    What is electric butterfly valve?

    An electric butterfly valve operates via an electric actuator that controls the rotational motion of the valve disc, either to initiate or halt fluid flow in a system. Belonging to the larger family of quarter-turn valves, this type of valve efficiently and reliably controls the flow. It manages a wide range of substances, showcasing our expertise in valve manufacturing industry. These range from gases and liquids to semi-solids and even solids, in numerous applications across various industries.

    The design of an electric butterfly valve typically incorporates one of three primary configurations: wafer, lug, or flange. Each of these configurations serves distinct purposes and offers unique benefits in its application:

    1. Wafer Butterfly Valves: These valves are named for their wafer-like thinness and are designed to maintain a seal against bidirectional pressure differentials in the system to prevent backflow. Wafer valves are an economical and space-saving solution suitable for systems where backflow is a potential issue.
    2. Lug Butterfly Valves: Lug valves come with threaded inserts at both sides of the valve body, which allows them to be installed into a system using bolt sets that attach directly to flanged pipe fittings. This type of valve can be easily installed or removed from a system without affecting other components. Thus, it’s an ideal choice for systems requiring regular maintenance or inspection.
    3. Flange Butterfly Valves: These valves have flanges on either side that are drilled to match the companion flanges on the pipe. The flange configuration provides a more robust and durable connection. This makes these valves suitable for high-pressure applications and large-diameter pipe installations.

    What are the features of an electric butterfly valve?

    When addressing the query about electric actuated butterfly valve features, it’s essential to delineate the characteristics. These distinguish this sophisticated component in the valve manufacturing industry. Electric butterfly valves are quintessential for their precise control, efficiency, and versatility across various sectors. These sectors include water treatment, HVAC systems, and industrial processing.

    The primary features of an electric butterfly valve include:

    1. Actuation Mechanism: The valve incorporates an electric actuator, which facilitates the opening and closing of the valve disc with precision. The electric actuator’s programmability for various control signals provides exceptional adaptability to different operational requirements. This showcases its versatility in meeting diverse industry needs.
    2. Sealing Technology: High-quality electric butterfly valves utilise advanced sealing technologies, such as PTFE (Polytetrafluoroethylene) or EPDM (Ethylene Propylene Diene Monomer) seals, ensuring excellent durability and resistance against a wide range of chemicals and temperatures. This makes them suitable for applications involving corrosive or abrasive fluids.
    3. Disc Material and Design: The material composition of the disc is crucial for the valve’s performance. Notably, common materials include stainless steel, ductile iron, or specialized alloys for heightened resistance to pressure, temperature, and chemical degradation. Furthermore, we optimize the disc’s design to minimize disruption to fluid flow, reduce pressure drops, and enhance efficiency. This demonstrates our unwavering commitment to precision engineering and unparalleled performance in the valve manufacturing industry.

    What is the main advantage of a butterfly valve?

    At the core of the butterfly valve’s superiority is its design. It enables quick and precise flow control with minimal pressure drop. This is accomplish through a disc that rotates within the valve body to open or close the flow path. This mechanism is straightforward and highly reliable. It requires significantly less maintenance compared to other valve types. This underpins our commitment to quality and lasting value.

    Furthermore, butterfly valves’ compactness and lightweight nature make them an ideal choice for new installations and retrofit projects. In the valve manufacturing industry, these qualities position them as leaders. Furthermore, their slim profile allows for efficient use of space – a critical factor in industrial applications where space economy is essential. This characteristic harmonizes with our global reach and expertise. Thus, we offer efficient, space-saving valve solutions tailored to meet international standards.

    What voltages does the electric butterfly valve have?

    Electric butterfly valves are integral components in regulating fluid flow within industrial applications. Additionally, they can operate across a spectrum of voltages, accommodating diverse system requirements and providing flexibility in installation and use. Moreover, the predominant voltage specifications for these valves include AC220V, AC380V, AC110V, and DC24V. This demonstrates our expertise in catering to various industry needs with precision.
