FAQ:
Integrated Electronics (OBE)
The "E" in DREE confirms On-Board Electronics (OBE). This means the valve contains its own amplifier. You supply 24V DC power and a 0–10 V command signal directly to the valve's K31 connector. This simplifies wiring and eliminates the need for an external VT-VSPA amplifier.
Mechanical Maximum Pressure Limiter (M)
The "M" immediately after DREE20 indicates the valve includes a mechanical safety relief valve as a maximum pressure limiter. This is a safety feature that hydraulically limits the maximum pressure at port A to approximately 350 bar, protecting the system in case of an electrical control fault.
Pressure Rating & Flow (200 bar / 300 L/min)
The "200" denotes the maximum electrically adjustable reduced pressure at port A. This is a high-flow variant (max flow 300 L/min), suitable for large actuator circuits or secondary pressure control in high-power systems.
External Pilot Drain (Y) & No Check Valve
"Y": The pilot control oil must be drained externally via port Y. This port must be connected directly to the tank with minimal backpressure. High backpressure at Y will cause inaccurate pressure regulation.
"M" at the end: The suffix "M" indicates no check valve is included between ports A and B. This means flow from port A back to port B is blocked by the spool design. If your application requires free reverse flow (A→B), you would need a variant without the final "M" code.
Critical Installation Notes
Port Y Drain: Must be piped separately to tank with a line diameter ≥ 5 mm and length < 2.5 m to avoid backpressure issues.
Zero Signal Pressure: With a 0 V command signal, the valve maintains a minimum pressure of approximately 2 bar at port A.
Subplate: Requires an NG20 subplate according to ISO 5781-AG-10-2-A (e.g., Rexroth RE 45102 series).
Correction: Your description mentioned "proportional relief valve", but this model is specifically a proportional pressure reducing valve. It controls the downstream (A-port) pressure, not the system relief pressure.
