Product Advantages
- Rigorous Quality Control: Every Yuming product undergoes a meticulous pressure test, ensuring you receive a pressure test report before it leaves our factory.
- High Performance Seat Rubber: With a rubber content of 50%, our seat rubber boasts an impressive switch life exceeding 30,000 cycles, guaranteeing longevity and reliability.
- Superior Soft Seat: Offering a broader contact surface than hard seats, our soft seats provide enhanced sealing performance during installation. Additionally, the butterfly valve's unique design negates the need for special flanges.
- Innovative Axial Seal: Supported by four oil-free bearings, the shaft features a dual-seal design with an O-ring and oil seal, ensuring smaller torque and dependable sealing.
- Durable Surface Coating: Our epoxy powder coating exhibits strong adhesion and exceptional weather resistance, making it suitable for both indoor and outdoor applications.
- Robust Ductile Iron Handle: Crafted from ductile iron, our handle surpasses stamping handles in strength, corrosion resistance, and durability. Its end handle, designed with a half-round structure, offers a smooth, comfortable grip without any sharp edges.
- Blow-Off Resistant Shaft Design: Our no-pin butterfly valve features an anti blow-off structure, allowing the handle to be changed under pressure for added convenience.
