High Pressure ilter Kits H 9 H 9 H 7 H 9 H 9 H 9 Operating pressure up to bar Nominal flow rate up to l/min escription Application In the high pressure circuits of hydraulic systems. Performance features Protection against wear: y means of filter elements that, in full-flow filtration, meet even the highest demands regarding cleanliness classes. Protection against malfunction: Through installation near to the control valves or other expensive components. The specific determined flow rate guarantees a closed by-pass valve even at ν mm /s (cold start condition). ilter elements low direction from outside to centre. The star-shaped pleating of the filter material results in: large filter surfaces low pressure drop high dirt-holding capacities long service life High Pressure ilter Kit H 9 ilter maintenance y using a clogging indicator the correct moment for maintenance is stated and guarantees the optimum utilization of the filter life. Materials ilter bowl: oating: Seals: ilter media: old extruded steel Powder paint NR (PM on request) XAPOR MAX - inorganic multi-layer microfibre web Accessories To monitor the clogging, screw-in (see section imensions) or flange-mounted differential pressure switches are available. lange-mounted clogging indicators optionally with one or two switching points resp. temperature suppression imensions and technical data see catalogue sheet..

Quality Assurance Quality management according to IN N ISO 9 To ensure constant quality in production and operation, ARGO-HYTOS filter elements undergo strict controls and tests according to the following ISO standards: ISO 9 ISO 9 ISO 9 ISO 9 ISO 9 ISO Verification of collapse/burst pressure rating Verification of fabrication integrity (ubble Point Test) Verification of material compatibility with fluids valuation of pressure drop versus flow characteristics Multi-Pass-Test (evaluation of filter fineness and dirt-holding capacity) etermination of resistance to flow fatigue using high viscosity fluid efore release into the series production the filter casing is tested for fatigue strength in our pressure pulse test rig. Various quality controls during the production process guarantee the leakfree function and solidity of our filters. Illustrations may sometimes differ from the original.
