Product Advantages
  1. Pressure Test Assurance: Every Yuming product undergoes rigorous pressure testing, with detailed reports provided before it leaves the factory, ensuring the highest standards of quality and reliability.
  2. High-Performance Seat Rubber: Engineered with 50% rubber content, our seat rubber guarantees over 30,000 switch cycles, offering unparalleled durability and longevity.
  3. Enhanced Soft Seat Design: Our soft seat provides a broader contact surface between pipes and flanges compared to hard seats, significantly improving sealing performance during installation. No special flange for the butterfly valve is required.
  4. Advanced Axial Seal: Supported by four oil-free bearings, our shaft features a dual seal design with both o-ring and oil seal. This results in reduced torque and highly dependable sealing.
  5. Durable Surface Coating: We utilize epoxy powder coating known for its strong adhesion and excellent weather resistance, making our valves suitable for both indoor and outdoor applications.
  6. Robust Ductile Iron Handle: Crafted from high-strength ductile iron, our handle outperforms stamped handles in strength, corrosion resistance, and durability. The half-round design ensures a comfortable grip with no sharp edges.
  7. Blow-Off Resistant Shaft Design: Featuring an anti blow-off structure, our no-pin butterfly valve allows for handle replacement under pressure, enhancing safety and convenience.
