Catalog excerpts

Bellows series valves Bellows valve feature a:The valve body adopts investment casting technology.Advanced technology to ensure that the valve body has no sand holes, surface more smooth and quality more reliable. b:Conical sealing surface will remove impurity automatically. c:Flexible pin, easy to replace the disc when broken. d:Bellow is the key part of bellow sealed valves,which is welded to both the valve bonnet and valve stem, with automatic roll welding. The metal bellow can keep the stem part100% no leakage. e:Three layers stainless steel bellows can be use 5000 times. f:The upper end of the bellows is welded to the bowl plate, and the lower end is welded to the valve stem to ensure that the medium does not leak from the valve stem. g:The guide piece limit the valve to open and close, better to protect the valve. h:Graphite packing was the second sealing for valves. i:Ergonomic hand wheel. It provide longer service life and easier Operation.
