Product Advantages
  1. All products can provide the pressure test: All Yuming products come with a comprehensive pressure test report before they leave the factory, ensuring reliability and top-notch performance.
  2. High performance seat rubber: Featuring a robust rubber content of 50%, this high-performance seat guarantees a switch life exceeding 30,000 cycles.
  3. Soft seat: Unlike hard seats, our soft seats offer a broader contact surface between pipes and flanges, significantly enhancing installation sealing performance. No special flange for the butterfly valve is required.
  4. Axial seal: Designed with precision, the shaft is supported by four oil-free bearings, incorporating a dual seal structure with an O-ring and oil seal. This design ensures smaller torque and unmatched reliability.
  5. Surface coating: Our valves feature an epoxy powder coating that boasts strong adhesion and superior weather resistance. Suitable for both indoor and outdoor applications.
  6. Ductile iron handle: Crafted from ductile iron, this handle offers enhanced strength, superior corrosion resistance, and outstanding durability compared to stamping handles. Its half-round design eliminates edges and corners, providing a comfortable grip.
  7. The design of shaft is blow-off resistant: Featuring an anti blow-off structure, the no-pin butterfly valve design allows handle changes even under pressure.
