Pressure Reducing Valve DREE20-6X/200YG24K31A1M - Bosch Rexroth R901243781

A branch circuit has to run permanently at less pressure than the pump supplies. The DREE20-6X/200YG24K31A1M handles that duty in size 25 and follows a 0...10 V command value steplessly, at up to 315 bar operating pressure and 300 l/min flow.

Benefits

• Command value 0...10 V at the on-board electronics, 24 V DC supply.
• Size 25 on connection diagram ISO 5781, three ports, two switching positions.
• Operating pressure to 315 bar at a flow of up to 300 l/min.
• Spool symbol B to A, hydraulic fluid HL.
• NBR seals, 6.17 kg, 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve sits in a branch of the machine hydraulics and holds a lower pressure level there than the main circuit. Typical duties are clamping and holding steps where the force changes during the cycle. The reduced pressure can be driven from the controller.
