US Standard Full Port Design Bellows Globe Valve for Pharma/Fertilizer Pipelines Low Emission Type-Marine Supplies

Petroleum, chemicals, pharmaceuticals, fertilizers, electricity

1. The bellows-sealed stop valve, whose key component is the metal bellows, is automatically rolled welded with the valve stem assembly at the lower end and the connecting plate at the upper end, 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, with better sealing performance and longer service life.
3. The double sealing design (bellows + packing) will prevent leakage if the bellows fails, and it meets 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 thread.
5. The ergonomically designed handwheel has a longer service life, easy and convenient operation, and is safer and more reliable.
