Dry TechnologySystematic fi tting selection B2 Catalogue 4100-9/UKIntroductionProduct selectionUltimate target is to fi nd the “best solution”. This optimum solution provides high system reliability, easy assembly characteristics, low maintenance effort and avoids the use of exotic components.This “best solution” is not the ultimately achieveable tech-nology, but an adequate solution which fulfi ls the require-ments of the individual application with minimum system cost.The “best solution” looks different depending on the spe-cifi c criteria of the given application.Dry TechnologyModern TFDE fi ttings are designed for high reliability, easy assembly and lowest toal cost performance.These products are marked Dry Technology and indicated grey in selection charts.Parker recommends to select only Dry Technology products for all new designs.Design criteria for fi tting selectionStep 1First clarify all design criteria for the given application or project.Step 2Then determine the “best solution” product. Use selection charts on following pages.Application● Hydraulic● Pneumatic● central lubrication● process industry● severenessAssembly● Mass production● On-site installation● Industrial assembly● Field repairSpecifi cations● International standards● End user specifi cation● approvals● availabilityEnvironment● weather● humidity● Stationary/mobileSpace● Space limitations● Tube bending capabilitiesFlow rate● Volume fl ow● medium viscosity● System dynamics● Tube selectionMedium● hydraulic oil type● Compressed air● Water/seawater● other fl uidsTemperature● Medium● Environment● Operation/standstillPressure● System pressure● Pressure peaksBest solution● zero leakage● high reliability● easy assembly● low total cost● standard prod...
