Product Advantages
  1. Rigorous Quality Control: Every Yuming product undergoes a meticulous pressure test, ensuring you receive a pressure test report before it leaves our factory.
  2. High Performance Seat Rubber: With a rubber content of 50%, our seat rubber boasts an impressive switch life exceeding 30,000 cycles, guaranteeing longevity and reliability.
  3. Superior Soft Seat: Offering a broader contact surface than hard seats, our soft seats provide enhanced sealing performance during installation. Additionally, the butterfly valve's unique design negates the need for special flanges.
  4. Innovative Axial Seal: Supported by four oil-free bearings, the shaft features a dual-seal design with an O-ring and oil seal, ensuring smaller torque and dependable sealing.
  5. Durable Surface Coating: Our epoxy powder coating exhibits strong adhesion and exceptional weather resistance, making it suitable for both indoor and outdoor applications.
  6. Robust Ductile Iron Handle: Crafted from ductile iron, our handle surpasses stamping handles in strength, corrosion resistance, and durability. Its end handle, designed with a half-round structure, offers a smooth, comfortable grip without any sharp edges.
  7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valve features an anti blow-off structure, allowing the handle to be changed under pressure for added convenience.
