Pressure Reducing Valve DREM20-6X/100YMG24K4M - Bosch Rexroth R901525929

Changing clamping pressures can only be set on a hand-adjusted valve while a machine stands still. The pressure reducing valve DREM20-6X/100YMG24K4M in size 25 takes an electrical command value and controls reduced pressure during a running cycle, at up to 300 l/min and a maximum of 315 bar operating pressure.

Benefits

• Electrical with external electronics, a command value comes from a machine control system.
• Up to 300 l/min at a maximum of 315 bar in size 25.
• Spool symbol B to A with three ports and two switching positions.
• Connection diagram ISO 5781 for subplate mounting in a manifold.
• 8 kg, NBR seals for HL hydraulic fluid at 24 VDC.

Application

It controls clamping, contact and counter-holding pressures in presses, winding lines and test rigs. Because a command value is electrical, pressure can be stored in a program and recalled per workpiece. An output stage sits outside this valve and is ordered separately.

Manufacturer

Bosch Rexroth lists this proportional pressure reducing valve DREM20-6X/100YMG24K4M under material number R901525929. Data sheets RE 29276 and RE 07600-B show characteristic curves, installation dimensions and the connection diagram. Operation calls for a matching external amplifier, since no electronics are built into this valve.
