Welded Bonnet Gate Valve. #weldedbonnetvalve #weldedbonnetgatevalve

Welded connection bonnet structure is not only economical but also reliable, and is not limited by valve size, operating pressure and temperature. But its disadvantage is that it is difficult to maintain, and the inside of the valve can only be accessed if the welding seam is removed. Therefore, welded bonnets are usually only used for long-term maintenance-free valves, disposable valves, or valves where sealing the bonnet connection is more difficult than disassembling the valve for overhaul.
