Product Advantages
- All products can provide the pressure test: Yuming Valve Group Co., Ltd ensures that all products, including the CF8 Disc Wafer Butterfly Valve, Butterfly Valve, and Soft Seal Viton Seat, undergo a thorough pressure test before leaving the factory, with a comprehensive report provided.
- High performance seat rubber: Boasting a rubber content of 50%, our high-performance seat rubber guarantees a switch life exceeding 30,000 cycles, ensuring long-lasting reliability.
- Soft seat: Our soft seat design, featuring a wider contact surface between pipes and flanges compared to hard seats, enhances sealing performance during installation. No special flange is needed for the butterfly valve.
- Axial seal: Engineered for excellence, the shaft is supported by four high-quality oil-free bearings, combining an o-ring and oil seal double seal structure. This design offers lower torque and improved sealing reliability.
- Surface coating: We utilize epoxy powder coating, known for its strong adhesion and outstanding weather resistance, making our products suitable for both indoor and outdoor applications.
- Ductile iron handle: Crafted from robust ductile iron, our handle surpasses the strength and corrosion resistance of traditional stamping handles. Its ergonomic half-round structure design ensures no sharp edges, providing a comfortable grip.
- The design of shaft is blow-off resistant: Our innovative no-pin butterfly valve features an anti-blow-off structure, allowing the handle to be replaced even under pressure, enhancing safety and convenience.
