    Product Description
    Butterfly valves function on a straightforward yet effective principle, relying on a central disc rotated by a stem to control fluid passage. This disc, when aligned with the pipeline, allows unobstructed flow, while a 90-degree rotation seals the passage completely—making the valve ideal for on-off or throttling applications.

    The key components driving performance include the disc, stem, body, and sealing assembly. Disc designs vary by application: resilient-seated discs offer tight closure for low-pressure systems, while metal-seated options withstand high temperatures and abrasive media. The stem, often connected to manual handles or automated actuation systems, ensures precise disc positioning, with anti-leakage features preventing fluid loss at the stem-body interface.

    Compared to other valve types, butterfly valves deliver distinct benefits: their compact profile reduces installation space, and the minimal pressure drop across the disc enhances energy efficiency. They also excel in rapid operation, with quick opening/closing cycles that minimize process downtime. These traits make them suitable for scenarios ranging from municipal water distribution to light industrial fluid handling, where reliability and cost-effectiveness are paramount.

    Frequently Asked Questions
    What is the working principle of a wafer butterfly valve?
    A wafer butterfly valve regulates fluid flow using a central disc mounted on a rotating stem. When aligned with the flow direction, the valve is fully open. Rotating the disc 90 degrees blocks the passage completely, providing a tight seal for either shut-off or flow regulation.
    What materials are used for the body and sealing components?
    The valve body and disc are made of durable Ductile Iron, the shaft is constructed from SS304 or SS316 stainless steel, and the sealing seat is made of PTFE (Teflon) to ensure excellent chemical resistance and tight sealing.
    What are the main advantages of butterfly valves over other valve types?
    Butterfly valves feature a compact, lightweight profile that saves installation space, creates minimal pressure drop for better energy efficiency, and allows for rapid opening and closing cycles to reduce operational downtime.
    Which standards do these wafer butterfly valves comply with?
    These valves are designed to meet major international standards, including DIN, ANSI, GOST, JIS, and BS, ensuring compatibility with global piping configurations.
    What operation methods are available for these valves?
    They can be operated manually using a Handle or Worm gear, or fully automated using Electric, Hydraulic, or Pneumatic actuators depending on system requirements.
