Unmatched Product Advantages
  1. Pressure Testing Excellence: Every Yuming product undergoes rigorous pressure testing, complete with a detailed test report before leaving our factory.
  2. Superior Performance Seat Rubber: Boasting 50% rubber content, our seats ensure a remarkable switch life exceeding 30,000 cycles.
  3. Enhanced Soft Seat: Offering a broader contact area between pipes and flanges compared to hard seats, our design delivers superior sealing performance without the need for special butterfly valve flanges.
  4. Innovative Axial Seal: Our shaft is supported by four oil-free bearings, featuring an O-ring and oil seal double structure for reduced torque and reliable sealing.
  5. Durable Surface Coating: We use epoxy powder coating for its strong adhesion and excellent weather resistance, making it perfect for both indoor and outdoor applications.
  6. Robust Ductile Iron Handle: Crafted from ductile iron, our handle surpasses stamping alternatives in strength, corrosion resistance, and durability. The ergonomic half-round end design ensures a comfortable grip with no sharp edges.
  7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valve features an anti blow-off structure, allowing handle changes under pressure with ease.
