By taking the drain line directly to tank,back pressure effects are negated.OPERATIONAs with the direct acting relief valves, when the pressureexceeds the spring force, the spool moves back,opening the inlet to outlet.PRESSURE DROPPRESSURE-BARPRESSURE-BAR0200175150125100755025504030201002.5 5.0 7.5 10 12.5 1530001DS3010FLOW-US GPM2030FLOW LITRES/MINFLOW-US GPM0 10 20 301DS1004050602500200015001000500040800600400200PRESSURE-PSIPRESSURE-PSIFEATURESStable, quiet operation.
