Product Advantages
  1. Comprehensive Pressure Testing: Every Yuming product comes with a detailed pressure test report before leaving the factory, ensuring unparalleled reliability and performance.
  2. Exceptional High-Performance Seat Rubber: Our rubber seats boast a 50% rubber content, guaranteeing an impressive switch life exceeding 30,000 cycles.
  3. Superior Soft Seat Advantages: Unlike hard seats, our soft seat design provides a broader contact surface between pipes and flanges, enhancing sealing performance. This design also eliminates the need for special flanges for butterfly valves.
  4. Innovative Axial Seal Design: Featuring a shaft supported by 4 oil-free bearings, and an O-ring and oil seal double seal structure, our valves offer reduced torque and reliable sealing.
  5. Durable Surface Coating: We utilize epoxy powder coating for strong adhesion and excellent weather resistance, making our valves suitable for both indoor and outdoor environments.
  6. Robust Ductile Iron Handle: Crafted from ductile iron, our handles provide superior strength, enhanced corrosion resistance, and exceptional durability. The half-round end handle design ensures a comfortable grip without sharp edges.
  7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valves feature an anti blow-off structure, allowing handle replacement under pressure for added convenience and safety.
