Valve Wheel Spanners / Wrenches / Keys, are manufactured to aid the turning of valve wheels used in the petrochemical industry.                                                                                  These tools are available in the following sizes: 8" (200mm), 12" (303mm), 18" (460mm), 24" (610mm), 36" (915mm). All sizes are manufactured as solid forgings. (Why Solid Forged)  Some companies manufacture them as a fabricated unit, but this usually requires two welds, which could produce a stress point causing the tool to fail when in use.  Please be aware that some companies OFFER 18", 24" & 36" sizes as 'EXTENDED' versions of the smaller sizes.  'EXTENDED'  means there is some form of mechanical extension, rather than a totally  'solid forged' Wheel Spanner.                                                                                                                                                 View our forging facilities here Our stock perforated sheet  here Standard and bespoke filters  more....
