Proportional Pressure Relief Valve Type N-DBEP06

ISO4401 Size 03 (NB06) General Description Proportional pressure relief valves Type N-DBEP06 are designed for limiting the pressure in a hydraulic system in proportion to an applied electrical input. These open-loop, single-stage valves can be used for di-rect control of pressure in low flow systems (max. 3L/min), or for pilot control of larger pressure controls, and for such applications as pressure-controlled pumps. Benefits

• Low hysteresis • Good repeatability • When used for piloting, a fast and stable response to step input signals is obtainable

Sizes

• Maximum Operating pressure : 350 bar • Rated flow : 1 L/min
