Product Advantages
  1. All products can provide the pressure test: All Yuming products are meticulously tested for pressure and accompanied by a comprehensive pressure test report prior to factory dispatch.
  2. High performance seat rubber: Featuring a rubber content of 50%, our seat rubber promises durability with a switch life exceeding 30,000 cycles.
  3. Soft seat: Unlike hard seats, our soft seat offers a broader contact surface between pipes and flanges, enhancing sealing performance during installation and negating the need for special butterfly valve flanges.
  4. Axial seal: Designed with 4 oil-free bearings supporting the shaft, our axial seal incorporates a dual seal structure with an o-ring and oil seal, ensuring reduced torque and reliable sealing.
  5. Surface coating: We utilize an epoxy powder coating renowned for its strong adhesion and excellent weather resistance, making our products suitable for both indoor and outdoor applications.
  6. Ductile iron handle: Crafted from ductile iron, our handle offers superior strength, enhanced corrosion resistance, and exceptional durability compared to stamping handles. Its half-round end design eliminates edges and corners, ensuring a comfortable grip.
  7. The design of shaft is blow-off resistant: Our no-pin butterfly valve features an anti-blow-off structure, allowing for handle changes under pressure without compromising safety.
