Product Advantages

1. Pressure Test Assurance: All Yuming Valve Group Co., Ltd products undergo rigorous pressure testing, with comprehensive test reports provided before they leave the factory.
2. High-Performance Seat Rubber: Featuring a 50% rubber content, these seats offer an impressive switch life exceeding 30,000 cycles.
3. Enhanced Soft Seat: Compared to hard seats, the soft seat has a wider contact surface between pipes and flanges, ensuring superior sealing performance upon installation without requiring special flanges for the butterfly valve.
4. Reliable Axial Seal: The shaft is supported by four oil-free bearings, with a dual seal structure consisting of an O-ring and oil seal, ensuring smaller torque and dependable sealing.
5. Robust Surface Coating: Our epoxy powder coating provides strong adhesion and exceptional weather resistance, making the valve suitable for both indoor and outdoor use.
6. Ductile Iron Handle: Crafted from ductile iron, this handle boasts superior strength, corrosion resistance, and durability compared to stamped handles. Its half-round design ensures a comfortable grip with no sharp edges.
7. Blow-Off Resistant Shaft Design: Our no-pin butterfly valve features an anti blow-off structure, allowing the handle to be changed under pressure.
