Rexroth Proportional pressure relief valve DBE,DBEE

1. Rexroth DBE Series: The DBE series of proportional pressure relief valves is designed for direct pressure control in hydraulic systems. These valves can adjust the pressure in real-time based on the electrical input signal they receive. They are often used in applications where a precise and proportional pressure control is required, such as in injection molding machines, hydraulic presses, and hydraulic test stands.

2. Rexroth DBEE Series: The DBEE series of proportional pressure relief valves is designed for pilot pressure control applications. These valves work in conjunction with a pilot pressure signal to control the main relief valve. They offer a high dynamic response and precise pressure control, making them suitable for applications where rapid pressure adjustments are needed. The DBEE valves are often used in hydraulic systems that require load-independent pressure control or in applications where the pilot signal can be sourced from a separate control circuit.
