Product Advantages
- Comprehensive Pressure Testing: All Yuming Valve Group Co., Ltd's products undergo rigorous pressure testing, ensuring the highest quality and reliability before leaving our factory.
- Superior High-Performance Seat Rubber: Featuring a rubber content of 50%, our valves guarantee exceptional durability with a switch life exceeding 30,000 cycles.

- Advanced Axial Seal Technology: Supported by four oil-free bearings, our diaphragm shaft features a dual-seal structure with both o-ring and oil seal, ensuring reduced torque and unparalleled sealing reliability.
- Durable Surface Coating: Our valves feature an epoxy powder coating that boasts strong adhesion and excellent weather resistance, making them suitable for both indoor and outdoor applications.
- Robust Ductile Iron Handle: Crafted from high-strength ductile iron, our handles offer superior corrosion resistance and durability compared to stamped handles. The ergonomic half-round design enhances user comfort and safety.
- Innovative Blow-off Resistant Shaft Design: Our no-pin butterfly valves include an anti blow-off structure, allowing handle changes under pressure for added convenience and safety.
