    High performance butterfly valve

    Introducing the High-Performance Butterfly Valve: Revolutionizing Reliability, Efficiency, and Durability

    The High performance Butterfly Valve is specifically designed to address the needs of various industries by providing top-quality sealing, longevity, and effortless operability. Unlike conventional butterfly valves, our High-performance Butterfly Valve stands out through its innovative design, advanced features, and proven reliability for a wide range of applications.Lug Butterfly Valves

    Key Benefits and Features

    • Seat Retainer Support: This one-of-a-kind design enables easy changeout of the seat, significantly reducing downtime during maintenance and parts replacement.
    • Double Offset Disc: The valve’s double offset disc design drastically minimizes torque, which translates to improved efficiency and durability.
    • Alloy Harden Disc Surface: By incorporating an alloy harden disc surface for metal seats, our valve ensures increased sealing life, leading to longer-lasting performance.
    • Integral Disc Stop: This additional feature prevents disc over-travel, further contributing to the valve’s durability and reliable performance.
    • Replaceable Seat Options: Our soft seat, fire-safe seat, and metallic seat options are fully interchangeable, allowing for tailored performance and industry-specific solutions.
    • PTFE Lined SS316 Bearing: To support the stem and increase service life, our High-performance Butterfly Valve utilizes PTFE lined SS316 bearings, thus offering superior corrosion resistance.
    • Thrust Ring for Anti-Blowout and Anti-Static: This advanced feature safeguards against potential hazards and ensures consistent, safe performance.

    Improved Efficiency, Profitability, and Sustainability

    The high performance butterfly valve manufacturers advanced design and capabilities translate to tangible benefits for a wide array of industries. With features like easy changeout, replaceable seat options, and improved durability under corrosion, this valve is a valuable asset that contributes to both the efficiency and effectiveness of any operation.

    Straightforward maintenance and increased service life lead to reduced long-term costs and improved profitability for businesses. Moreover, our valve’s design encourages sustainability by promoting fewer replacements and waste generation.

    High performance butterfly valves provides a cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve yet easier operating, longer lasting and lower cost.

    Significant performance makes the valve widely used in many applications such as Airport refueling, Hydrocarbon processing, HVAC, Air treatment, Chemical processing, Purified gas, Steam and vacuum services, Potable water, Powder and pulp processing, etc. Wafer design makes the valve convenient for connection between flanges and save length in pipe line.

    FEATURES

    • One-piece stem design with ISO 5211 square drive
    • ISO 5211 direct mounting flange on the valve body
    • Easy-adjust gland packing accessible with actuator mounted in place
    • Belleville washers on the gland nut offer reliable primary sealing between shaft and packing
    • Retaining ring for both equably pressing on packing and stem blowout proof
    • Multiply rows of RPTFE chevron for soft seat valve and Graphite chevron for fire safe and metallic seat
    • Extended neck for pipe insulation
    • Self-energized seat resulting in longer life and reduced maintenance·Pin-less shaft to disc connection makes the valve convenient for parts replacement and reliable even under corrosion
    • Seat retainer supports the seat and allows for easy changeout
    • Double offset disc reducing the valve torque
    • Alloy harden disc surface for metal seat increases the sealing life time
    • Integral disc stop prevent disc from over travel
    • Soft seat, fire safe seat and metallic seat are replaceable each other
    • PTFE lined SS316 bearing support stem and increase service life
    • Thrust ring for anti-blowout and anti-static
