Product main advantages

1. Bellows sealed stop valve, its key component is the metal bellows, the lower end of which is automatically seam welded to the valve stem assembly, and the upper end is automatically seam welded to the connecting plate, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem.

2. The valve disc adopts a conical design, and the sealing surface and the medium are streamlined, which has better sealing performance and longer service life.

3. Double sealing design (bellows + packing) If the bellows fails, the valve stem packing will also avoid leakage and meet international sealing standards.

4. The valve cover is equipped with a grease joint, which can directly lubricate the valve stem, nut and sleeve, unlike the traditional method of only adding lubricating oil to the threads.

5. Ergonomically designed handwheel, longer service life, easy and convenient operation, safer and more reliable
