Product Advantages
- Pressure Test Assurance: Every Yuming product undergoes a rigorous pressure test, and we provide a detailed pressure test report before the product leaves our factory.
- High-Performance Seat Rubber: Our seat rubber boasts a 50% rubber content and guarantees a switch life exceeding 30,000 cycles, ensuring long-lasting durability.
- Soft Seat Excellence: Unlike a hard seat, our soft seat offers a wider contact surface between pipes and flanges, enhancing the sealing performance during installation. Moreover, it eliminates the need for a special flange for the butterfly valve.
- Superior Axial Seal: The shaft features support from four oil-free bearings and a dual seal structure design with an o-ring and oil seal, resulting in lower torque and a more reliable seal.
- Durable Surface Coating: Our products are coated with epoxy powder, providing strong adhesion and excellent weather resistance. This makes them suitable for both indoor and outdoor applications.
- Robust Ductile Iron Handle: Manufactured from ductile iron, our handle offers superior strength, enhanced corrosion resistance, and greater durability compared to stamping handles. The half-round structure design at the end of the handle ensures a comfortable grip without edges and corners.
- Blow-Off Resistant Shaft Design: Our no-pin butterfly valve incorporates an anti blow-off structure, allowing the handle to be changed under pressure, ensuring safety and convenience.
