Product Overview
The Rexroth 3DREME 10P-73/315YG24K31A1V (material number R901240745) is a direct-operated, three-way proportional pressure reducing valve from the Bosch Rexroth DREME series. It is designed to convert an electrical input signal into a continuously variable, infinitely adjustable reduced outlet pressure, providing precise electro-hydraulic control of secondary pressure circuits in industrial hydraulic systems. The valve operates on a proportional solenoid principle: the solenoid force acts directly against a pressure-setting spring and the feedback pressure at the control spool, establishing a force balance that determines the regulated output pressure. This three-way configuration (P, A, T ports) permits both pressure reduction and pressure relief of the consumer line, making it suitable for applications requiring accurate, dynamic pressure regulation independent of flow demand. The 3DREME 10P-73/315YG24K31A1V is a direct replacement component for Rexroth proportional pressure control circuits and is widely used in machine tools, injection molding equipment, and general industrial hydraulic power units.
