Product Advantages

1. All products can provide the pressure test: At Yuming Valve Group Co., Ltd, every product is meticulously tested to ensure quality. We provide comprehensive pressure test reports before any product leaves our factory premises.
2. High performance seat rubber: Featuring an impressive 50% rubber content, our seat rubber offers an exceptional switch life of over 30,000 cycles, guaranteeing durability and reliability.
3. Soft seat: Our soft seat design boasts a wider contact surface between pipes and flanges compared to hard seats. This results in superior sealing performance during installation, eliminating the need for a special flange for the butterfly valve.
4. Axial seal: Engineered for excellence, the shaft is supported by four oil-free bearings and features an O-ring and oil seal double seal structure. This design ensures reduced torque and a dependable seal.
5. Surface coating: We utilize epoxy powder coating for our products, ensuring strong adhesion and excellent weather resistance. This makes our valves suitable for both indoor and outdoor applications.
6. Ductile iron handle: Crafted from high-strength ductile iron, our handles offer superior strength, enhanced corrosion resistance, and remarkable durability compared to stamping handles. The half-round structure design ensures no edges or corners, providing an excellent tactile experience.
7. The design of shaft is blow-off resistant: Our innovative no-pin butterfly valve incorporates an anti blow-off structure, allowing the handle to be changed under pressure for added flexibility and safety.
