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.

2 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) working Pressure - Spool-type valves - valves with calibrated ports-/18/14- Equipment running at low working Pressure - Pilot plants and equipment- Equipment with low frequency cycles-/19/15mminD1 WWEM01E4 DIVISIONDIVISIONH ydraulic diagramHydraulic diagramHydraulic diagramHydraulic diagramTypeDescriptionMaximum flow up toMaximum pressurePagel/minUS gpmbarpsiVMPD irect acting, poppet type1002640058009 VMP Y160423154600MC100263505100 TypeDescriptionMaximum flow up toMaximum pressurePagel/minUS direct acting valves , poppet flow up toMaximum pressurePagel/minUS acting valves , poppet type10026350510033 TypeDescriptionMaximum flow up toMaximum pressurePagel/minUS gpmbarpsiVMPDD ifferential-control, poppet relief VALVESH ydraulic diagramTypeDescriptionMaximum flow up toMaximum pressurePagel/minUS operated propor-tional Pressure relief valve with inverse function.
