Product Advantages
  1. Comprehensive Quality Assurance: All Yuming products undergo rigorous pressure testing, ensuring each product meets the highest standards before leaving our factory.
  2. High-Performance Seat Rubber: Crafted with 50% rubber content, our seats boast an impressive switch life exceeding 30,000 cycles, providing durability and reliability.
  3. Superior Soft Seat Design: Our soft seat offers a wider contact surface between pipes and flanges compared to hard seats, enhancing sealing performance significantly. This design eliminates the need for special butterfly valve flanges.
  4. Innovative Axial Seal: Featuring a double-seal structure with o-rings and oil seals, supported by four oil-free bearings, our axial seal provides reduced torque and reliable performance.
  5. Durable Surface Coating: We utilize epoxy powder coating, known for its strong adhesion and excellent weather resistance, making our valves ideal for both indoor and outdoor applications.
  6. Robust Ductile Iron Handle: Our handle, made from ductile iron, offers superior strength, enhanced corrosion resistance, and exceptional durability. The ergonomic half-round design ensures a comfortable grip without sharp edges.
  7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valve features an anti blow-off structure, allowing handle changes under pressure for added convenience and safety.
