DIN Bellow Seal Gate Valve

DIN Bellow Seal Gate Valve Introduction:

1. The bellows seal gate valve, the key component metal bellows, the lower end and the valve stem assembly are automatically seamed and welded, and the upper end and the connecting plate are automatically seamed and welded, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem .
2. Double sealing design (bellows + packing), in line with international sealing standards.
3. The valve cover has its own grease fitting, which can directly lubricate the valve stem, nut and bushing, unlike the traditional lubricating oil only on the thread.
4. Ergonomically designed handwheel, DN100 and above are impact type, longer service life and easier and more convenient operation.
