Product Features:
1. Double Sealing Design (Bellows + Packing)：If the bellows fails, the valve stem packing will also be avoided. The sturdy and durable bellows sealing design ensures zero leakage of the valve stem and provides maintenance-free conditions.
2.Reasonable Structure and Reliable Sealing: It has compact overall design, excellent sealing performance, and well-designed appearance.
3. No Fluid Loss: It has no fluid loss, which can reduce energy loss, and improve factory equipment safety.
4. Co-based Hard Alloy Sealing Surface: The sealing surface is surfacing welded Co-based hard alloy, which is wear-resistant, corrosion-resistant, and anti-friction, making it a long service life. It also reduces maintenance times and operating costs.
5. Bellows Sealing Design: Sturdy and durable bellows sealing design ensures zero leakage of the valve stem and provides maintenance-free conditions.
6.Anti-corrosion Performance: The stem of the bellows stop valve is tempered and nitrated on the surface, which has good anti-corrosion and anti-friction performance.
7.Limit Device: The valve sets the limit device to ensure that the bellows seal is not affected when switching.
8.The OS&Y design makes the valve opening and closing position clear, which is convenient for operation and monitoring. 9.Long Service Life Design: The valve has a long service life, which reduces maintenance times, and operating costs.
