Bellows seal gate valves, it is a key component of metal bellows, bottom stem adopts automatic seam welding and welding, the upper roll and connection plate automatic welding, between the fluid and the atmosphere to form a metal barrier, to ensure that the valve stem zero leakage.
2. Double seal design (corrugated pipe + packing) if bellows fail, stem packing will also avoid leakage and comply with international sealing standards;
3. The valve cover is equipped with grease fitting, which can be used directly to lubricate the stem, nut and shaft sleeve, not like the traditional screw lubrication.
4. Ergonomically designed handwheel, with longer service life, easy and convenient operation, safer and more reliable;
