2 For further safety of your hydraulic equipment and of all valves assembled on it, we either recommend use suction filters (rather than return filters) or separated filter :make sure to provide suitable gasket lubrication with clean oil before screwing the cartridge on the valve body . Also make sure to screw the cartridge manually in to reach against the gaskets in the valve :internal components made out of high grade steel duly treated and more information please ask our technical office .Working temperature:min. -25 C (-13 F) max. 90 C (194 F) with standard BUNA N -20 C (-4 F) max. 200 C (392 F) with optional VITON diagrams:all rating diagrams of this catalogue are measured with mineral oil of 46 cSt viscosity at 40 (104 F) drawings dimensions are defined as TYPE OF EQUIPMENT - TYPE OF VALVECONTAMINATION LEVELA ccording to ISO 4406- Heavy duty equipment- Equipment running at 210-350 bar (3050-5100 psi) working pressure- Equipment using proportional controls- Equipment with high frequency cycles-/16/13- Equipment running up to 210 bar (3050 psi)
