Product Advantages

1. All products can provide the pressure test: Every Yuming product comes with a comprehensive pressure test report, ensuring peak performance before leaving our facility. Trust in quality you can verify.
2. High performance seat rubber: Engineered with 50% rubber content, our seat rubber boasts an impressive switch life exceeding 30,000 cycles, guaranteeing longevity and reliability.
3. Soft seat: The soft seat design offers a broader contact surface between pipes and flanges compared to a hard seat, enhancing sealing performance during installation. Additionally, there's no need for a special flange for the butterfly valve.
4. Axial seal: Featuring a sophisticated design, the shaft is supported by four oil-free bearings and incorporates a double seal structure with an o-ring and oil seal. This results in reduced torque and a dependable seal.
5. Surface coating: Our epoxy powder coating provides exceptional adhesion and outstanding weather resistance, making our valves suitable for both indoor and outdoor applications.
6. Ductile iron handle: Crafted from ductile iron, the handle offers superior strength, enhanced corrosion resistance, and unparalleled durability. Its ergonomic, half-round design ensures a comfortable grip with no sharp edges.
7. The design of shaft is blow-off resistant: Ingeniously designed with an anti blow-off structure, the no-pin butterfly valve allows for handle changes under pressure, ensuring safety and ease of maintenance.
