3. Soft seat: The soft seat offers a broader contact surface between pipes and flanges compared to hard seats, enhancing sealing performance. Additionally, it eliminates the need for special flanges for butterfly valves.
4. Axial seal: Featuring a double seal structure with o-ring and oil seal, supported by 4 oil-free bearings, this design ensures lower torque requirements and reliable sealing.
5. Surface coating: Our epoxy powder coating ensures superior adhesion and excellent weather resistance, making it ideal for both indoor and outdoor applications.
6. Ductile iron handle: Crafted from ductile iron, our handle surpasses stamped handles in strength and corrosion resistance. Its unique half-round structure design provides a smooth, comfortable grip without edges or corners.
7. The design of shaft is blow-off resistant: Engineered with an anti blow-off structure, the no-pin butterfly valve allows for handle changes even under pressure, ensuring durability and safety.
