Flowforces are proportional to flow and pressure drop. Typically, they resist the opening of a passage. Spool configurations thatopen passages as they spring centre are the most susceptible. If the flow forces due to the flow and pressure conditionsexceed the centring spring force the valve may not shift completely. Higher flows may be used at lower pressures.NominalCapacityDC ✱ C – X ✱ ✱Control Spool Configuration Spool Configuration Seal Material666662C 40 L/min.
