    Frequently Asked Questions
    Q What is a U-type flanged butterfly valve and how does it differ from standard butterfly valves?
    The U-type flanged butterfly valve features a top-entry structure that minimizes the number of body connection bolts. Unlike standard butterfly valves, this design is specifically optimized for high-pressure and large-diameter applications, reducing the impact of system weight on valve performance and ensuring more stable operation.
    Q What pressure ratings are available for the U-type flanged butterfly valve?
    The U-type flanged butterfly valve is available in PN10 and PN16 pressure classes, with unbalance pressure ratings of up to 16 bar, covering a wide range of industrial pipeline applications.
    Q What seat materials are available for different media and temperature requirements?
    The valve seat can be supplied in EPDM, NBR, Neoprene, or VITON, allowing the valve to be matched to a wide variety of media including water, seawater, oils, and chemicals, as well as different temperature ranges.
    Q What actuator flange standards does this valve support?
    Depending on the valve size (DN), the U-type flanged butterfly valve supports actuator flanges including F07, F10/F12, F12, F14, and F16, in compliance with ISO 5211 standards. This ensures compatibility with a wide range of pneumatic, electric, and manual actuators.
    Q What body and disc material options are available?
    The valve body and disc are available in Ductile Iron (DI) and Cast Iron for the body, while the disc can be manufactured in DI, SS 304, or SS 316, providing options suited to both standard and corrosion-resistant service requirements.
    Q What is the available size range for this U-type flanged butterfly valve?
    The U-type flanged butterfly valve is available in sizes from DN 150 mm up to DN 600 mm, covering face-to-face lengths (L) from 56 mm to 153 mm, making it suitable for a wide range of pipeline diameters in industrial and municipal installations.
