The D71X series lever-operated wafer butterfly valve is available in high-quality cast iron, cast steel, or stainless steel bodies, combined with a wide range of disc, stem, and seat material options.
It is ideal for water treatment, chemical processing, food and beverage, pharmaceutical, and general industrial piping systems. With a compact wafer design and simple 90° lever operation, the valve provides reliable sealing, excellent corrosion resistance, and easy installation. Sizes range from DN50 to DN200, with pressure ratings PN10-PN16. Custom configurations are available to meet specific application requirements.
The D71X lever-operated wafer butterfly valve is a cost-effective and reliable industrial valve. Its wafer-style design minimizes space requirements and simplifies installation and maintenance. The lever handle enables quick 90° opening and closing, making it suitable for both on-off and basic throttling applications across a variety of fluid media.
