Subplates and Mounting SurfacesGeneral DescriptionWhen a subplate is not used, amachined pad must be provided forvalve mounting. Pad must be flat within0,0127 mm (.0005 inch) and smoothwithin 1,6 µm (63 microinch). Mountingbolts, when provided by customer,should be ISO 898 class 12.9 or better.SubplatesDimensional TolerancesDimensional tolerance on interfacedrawings is 0,2 mm (0.008”) exceptwhere otherwise stated. ISO 4401specifies inch conversion to 0.01”.Conversion from MetricISO 4401 gives dimensions in mm. Inchconversions are accurate to 0.01”unless otherwise stated.Mounting Bolt TappingsISO 4401 gives metric thread tappings.Alternate UNC tappings are Vickersrecommendations that allow theseplates and associated valves to be usedup to their maximum pressures, whenusing Vickers recommended bolt kits, orbolts of an equivalent strength. It isrecommended that Customer’s ownmanifold blocks for UNC bolts should betapped to the minimum depths given inthe footnotes.Description and Mass kg (lb) Functional Symbol Model Code Max.
