Product Advantages

1. Comprehensive Pressure Testing: Yuming Valve Group Co., Ltd ensures the highest quality by providing thorough pressure test reports for all products before they leave the factory.
2. High Performance Seat Rubber: Featuring a rubber content of 50%, our seat rubber guarantees a remarkable switch life of over 30,000 cycles.
3. Soft Seat Superiority: The soft seat design offers a broader contact surface between pipes and flanges compared to hard seats, enhancing sealing performance without requiring special butterfly valve flanges.
4. Innovative Axial Seal: With a robust design incorporating 4 oil-free bearings, an O-ring, and an oil seal double structure, our axial seal ensures lower torque and reliable sealing.
5. Durable Surface Coating: Our components are finished with an epoxy powder coating, providing strong adhesion and excellent weather resistance, suitable for both indoor and outdoor applications.
6. Robust Ductile Iron Handle: Made from ductile iron, our handles offer superior strength and corrosion resistance compared to stamped handles. The half-round end handle design ensures no sharp edges and a comfortable grip.
7. Blow-off Resistant Shaft Design: Our no-pin butterfly valve is engineered with an anti blow-off structure, allowing the handle to be changed under pressure.
