RE 6580/05.11 DR 10 DP Hydraulics osch Rexroth G 3/8 Function, section The valve type DR 10 DP is a direct operated pressure reducing valve in 3-way design, i.e. with pressure limitation of the secondary circuit. It is used to reduce a system pressure. The secondary pressure is set via the adjustment type (1). In the initial position the valve is open. Hydraulic fluid can flow from channel to channel without obstructions. Via the pilot line (4), the pressure in channel is applied to the spool face vis-à-vis the compression spring (3). If the pressure in channel rises above the value set at the compression spring (3), the control spool () moves into the control position and holds the set pressure in channel constant. Signal and pilot oil are provided internally, via the control line (4) by channel. If the pressure in channel continues to increase due to external forces at the actuator, it moves the control spool () further against the compression spring (3). Thus, channel is, via the control edge (5) at the control spool (), connected with channel T(Y). Hydraulic fluid flows to the tank until the pressure can only increase slightly. The leakage oil drain from the spring chamber (6) is always realized externally, via channel T (Y). For the free flow back from channel to channel, you can optionally install a check valve (7). pressure gauge connection (8) allows for the control of the secondary pressure. 7 5 8 4 1 3 6 T(Y) T(Y) Type DR 10 DP1-4X/.Y
