I. Core Structural Features
- Double-flanged connection The valve body has double flanged ends (conforming to the structural requirements of GB/T 12238 for double flanged butterfly valves), which are installed by bolt clamping, resulting in a compact structure and saving pipeline space;
- Handle drive Equipped with a lever handle (black handle in the picture), for manual quick opening and closing, with low operating torque (DN100 opening and closing torque ≤80N・m), suitable for frequent operation scenarios;
- Centerline soft seal The valve plate is made of ductile iron with an outer layer of EPDM rubber (black sealing layer in the picture), which fits tightly against the lined sealing surface of the valve body, with a bidirectional sealing leakage rate ≤0.01% (conforming to the sealing performance requirements of GB/T 13927).

Double-flanged handle butterfly valve D71X
The D71X double-flanged handwheel butterfly valve features a compact double-flanged design. The handwheel drive enables quick opening and closing, while the center-line soft seal ensures zero leakage. The ductile iron valve body is pressure-resistant and wear-resistant, and the EPDM seal is compatible with multiple media, fully complying with national standards such as GB/T 12238 and GB/T 13927.
Compact structure, convenient operation, and reliable sealing make it suitable for shut-off and regulation in small and medium-diameter pipelines in building water supply and drainage, HVAC, and light industry, providing a cost-effective solution for efficient pipeline operation and maintenance.
