Product Overview
The Rexroth DRE6X-11/175MG24-8NZ4M (Material Number: 0811402055) is a direct-operated, pilot-operated proportional pressure reducing valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. Part of the Rexroth DRE6X series, this valve operates on a proportional solenoid principle, where the output pressure is continuously adjusted in proportion to the electrical input signal. The DRE6X-11/175MG24-8NZ4M is engineered to reduce a higher inlet pressure to a lower, electrically commanded outlet pressure, making it ideal for applications requiring accurate pressure regulation, load compensation, and smooth dynamic response. With a nominal pressure rating of 175 bar and a 24 VDC proportional solenoid, this valve integrates seamlessly into modern electro-hydraulic control architectures, offering high resolution, low hysteresis, and excellent repeatability for demanding industrial processes.
