Product Description

Product Description

Product Advantages
  1. All products can provide the pressure test: All Yuming products come with a comprehensive pressure test report before they leave our factory, ensuring every valve meets the highest quality standards.
  2. High performance seat rubber: The rubber boasts a 50% content, delivering an impressive switch life exceeding 30,000 cycles.
  3. Soft seat: Our soft seats offer a wider contact surface between pipes and flanges compared to hard seats. This results in superior sealing performance during installation, negating the need for special flanges on the butterfly valve.
  4. Axial seal: The shaft is supported by four oil-free bearings, featuring a double seal structure with an o-ring and oil seal. This design ensures smaller torque and a highly reliable seal.
  5. Surface coating: We utilize epoxy powder coating, known for its strong adhesion and excellent weather resistance, making our valves suitable for both indoor and outdoor applications.
  6. Ductile iron handle: Crafted from durable ductile iron, our handle outperforms stamped handles in strength, corrosion resistance, and longevity. The half-round design at the end ensures a comfortable grip without sharp edges.
  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 changed safely even under pressure.
