Product Description

Unparalleled Product Advantages
  1. Comprehensive Pressure Testing: All Yuming products are meticulously pressure tested, and a detailed report is provided before the products leave our factory.
  2. Superior High-Performance Seat Rubber: Featuring 50% rubber content, this component ensures a remarkable switch life exceeding 30,000 cycles.
  3. Enhanced Soft Seat Design: Compared to hard seats, the soft seat offers a broader contact area between pipes and flanges, significantly improving sealing performance during installation. Furthermore, it negates the need for a special butterfly valve flange.
  4. Innovative Axial Seal: Our design incorporates a shaft supported by four oil-free bearings and a dual-seal structure with both o-rings and oil seals, ensuring minimal torque and a reliable seal.
  5. Durable Surface Coating: Employing epoxy powder coating, our products boast strong adhesion, excellent weather resistance, and suitability for both indoor and outdoor use.
  6. Robust Ductile Iron Handle: Crafted from ductile iron, this handle surpasses stamped handles in strength, corrosion resistance, and durability. Its end handle features a half-round structure design for a safe, smooth feel without sharp edges.
  7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valve is engineered with an anti blow-off structure, allowing the handle to be changed under pressure with ease.
