VALVE WHEEL SPANNER / VALVE WHEEL WRENCH8", 12", 18", 24", 36". All sizes are SOLID FORGEDProduced and stocked by: Robin J Green LtdValve 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. ROBIN J GREEN LTDUnit 6, Bakehouse Mews,Oxford Road,Yeovil, Somerset.
