Pressure Reducing Valve DRE20-6X/100YG24K4M - Bosch Rexroth R901344914

With size 25 this proportional pressure reducing valve covers the larger port cross-section of the DRE(M)(E)10,20 range and tracks the branch pressure to the electrical command value. Maximum operating pressure 315 bar, maximum flow 300 l/min, weight 6.04 kg, spool symbol B to A.

Benefits

• Size 25 with ISO 5781 subplate mounting and 3 ports for a maximum flow of 300 l/min.
• NBR seals for HL hydraulic fluid in a standard mineral oil circuit.
• Maximum operating pressure 315 bar - the reduced branch pressure stays independent of the higher system pressure.
• Electrical with external electronics actuation, 24 VDC supply voltage, 2 switching positions.
• Connector, 3-pole (2 + PE) according to EN 175301-803 for the electrical connection.
• 6.04 kg weight - a figure to account for when mounting on vertical valve blocks.

Applications

The larger port cross-section of size 25 targets presses, power units and machine tools in which a sub-circuit runs at reduced pressure while carrying a high flow. The external electronics allow a new pressure to be set for each step of the work cycle. Installation calls for a matching ISO 5781 subplate.
