Product Advantages
  1. Rigorous Quality Assurance: All Yuming products are meticulously examined and come with a comprehensive pressure test report prior to leaving our factory, ensuring top-notch reliability and performance.
  2. High Performance Seat Rubber: Boasting a substantial rubber content of 50%, this seat guarantees exceptional longevity, with a remarkable switch life exceeding 30,000 cycles.
  3. Soft Seat Superiority: Offering a broader contact surface between pipes and flanges compared to hard seats, our soft seats provide superior sealing performance. Additionally, they eliminate the need for special flanges, making installation more efficient.
  4. Revolutionary Axial Seal: Our innovative design supports the shaft with four oil-free bearings, complemented by a dual seal structure featuring an O-ring and oil seal. This results in reduced torque and unmatched reliability.
  5. Robust Surface Coating: Our products are finished with an epoxy powder coating, known for its excellent adhesion and exceptional resistance to weather conditions, making them suitable for both indoor and outdoor use.
  6. Durable Ductile Iron Handle: Constructed from ductile iron, our handles surpass stamped handles in strength, corrosion resistance, and durability. The ergonomic half-round 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, enabling handle changes even under pressure, thereby enhancing safety and convenience.
