The Rexroth DBE and DBEE series are both proportional pressure relief valves used in hydraulic systems to regulate and control the pressure of hydraulic fluid. These valves are designed to provide precise pressure control and dynamic response in various industrial applications where maintaining a specific pressure level is critical.
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.
