Stainless Steel Bellows Globe Valve
Features of Bellows Sealing Globe Valve
Bellows sealing globe valve, the key components is metal bellows, the bellows lower end and stem are connected by automatic rolling welding, the bellows top and the connection plate are connected by automatic rolling welding. Formed a metal barrier between the fluid medium and the atmosphere to ensure the stem zero leakage. globe valve,bellows globe valve,bellows sealing globe valve
The bellows globe valve disc is designed with a cone structure, with better sealing performance and longer service life. globe valve,bellows globe valve,bellows sealing globe valve
Double sealing design ( bellows + packing ), If the bellows sealing failed, stem packing will also avoid leakage. globe valve,bellows globe valve,bellows sealing globe valve
The bonnet comes with a fat liquoring connector, can directly lubricate on the stem, nut and sleeve, unlike the traditional valve which only lubricate on the thread.
