Product Advantages
  1. Comprehensive Pressure Testing: All Yuming products are rigorously pressure-tested, ensuring a detailed pressure test report accompanies each product before it leaves the factory.
  2. High-Performance Seat Rubber: Featuring a rubber content of 50%, our seats boast a switch life exceeding 30,000 cycles, promising longevity and reliability.
  3. Enhanced Soft Seat: Unlike hard seats, our soft seat design offers a broader contact surface between pipes and flanges, ensuring superior sealing performance without the need for special butterfly valve flanges.
  4. Reliable Axial Seal: Supported by four oil-free bearings, our shaft design incorporates an o-ring and oil seal double seal structure, ensuring lower torque and impeccable sealing.
  5. Durable Surface Coating: Utilizing epoxy powder coating, our valves achieve strong adhesion and exceptional weather resistance, suitable for both indoor and outdoor applications.
  6. Robust Ductile Iron Handle: Crafted from ductile iron, our handle outperforms stamped alternatives with superior strength, enhanced corrosion resistance, and greater durability. The half-round design ensures a comfortable grip with no sharp edges.
