Product Advantages
  1. All products can provide the pressure test: Each and every Yuming product is meticulously tested for pressure, ensuring a comprehensive pressure test report is available before it ever leaves our state-of-the-art factory.
  2. High performance seat rubber: With a robust rubber content of 50%, our seat rubber is engineered for high performance, boasting a switch life that exceeds 30,000 cycles.
  3. Soft seat: Unlike hard seats, our soft seat design features a wider contact surface between pipes and flanges, offering superior sealing performance during installation. No special flange is required for our butterfly valve.
  4. Axial seal: Featuring a shaft supported by four oil-free bearings, our design incorporates a double seal structure with O-rings and oil seals, ensuring reduced torque and enhanced reliability.
  5. Surface coating: Our valves are coated in epoxy powder, ensuring excellent adhesion and outstanding weather resistance, making them suitable for both indoor and outdoor applications.
  6. Ductile iron handle: Constructed from ductile iron, our handles outperform stamping handles with superior strength, enhanced corrosion resistance, and remarkable durability. The half-round, edge-free design ensures a comfortable grip.
  7. The design of shaft is blow-off resistant: Our no-pin butterfly valve features an anti blow-off structure, allowing the handle to be safely changed even under pressure.
