Bellow Seal Globe Valve Features

1. Bellows stop valve, its key component metal bellows, the lower end and the valve stem assembly adopt automatic roll welding, and the upper end is automatically welded with the connecting plate to form a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem.
2. Valve disc adopts parallel design, better sealing effect and long service life.
3. Double seal design (bellows + packing) in case of bellows failure and leakage, the valve stem packing will also avoid leakage and meet the international sealing standard.
4. The valve cover is equipped with a greasing joint, which can directly lubricate the valve stem, nut and shaft sleeve, unlike the traditional method of only lubricating the thread.
5. Ergonomic design handwheel, longer service life, easy and convenient operation, more safe and reliable.
