FAQ:
Integrated Electronics (OBE) & Closed-Loop
The "E" in DREBE confirms On-Board Electronics (OBE). This means the valve contains its own amplifier and LVDT position feedback sensor. You supply 24V DC power and a 0–10 V command signal directly to the valve's K31 connector. This closed-loop design provides high accuracy (hysteresis ≤1%) and eliminates the need for an external VT-5000 amplifier.
High Reduced Pressure Rating (310 bar)
The "310" denotes the maximum electrically adjustable reduced pressure at port A. This is the high-pressure variant of the DREBE series, allowing the secondary circuit to operate at near-system pressure levels with precise electronic control.
3-Way Pressure Reducing Logic
This valve operates as a 3-port device (P, A, T). It continuously compares the A-port pressure with the electrical setpoint. If the load pressure at A tries to exceed the setpoint (e.g., due to an overrunning load), the valve opens the A→T path to "dump" the excess pressure and maintain regulation.
No Check Valve (M)
The "M" in the suffix indicates no check valve is included. This means flow from port A back to port P is blocked by the spool design, but there is no free reverse flow path. For applications requiring free return flow, a different variant would be needed.
Critical Installation Notes
Direct Signal Connection: Connect 24V DC and 0–10 V signal directly to the K31 connector. Do not use an external amplifier.
Tank Line Backpressure: Port T must be connected to tank with minimal backpressure. High backpressure at T will be added to the A-port pressure, causing inaccurate regulation (P_A_effective = P_set + P_T_backpressure).
Pilot Flow: The valve uses an internal pilot supply (approx. 0.6 L/min), so no external pilot line is needed, but ensure your pump flow accounts for this constant consumption.
Correction: Your description mentioned "servo relief valve", but this model is specifically a proportional pressure reducing valve. It controls the downstream (A-port) pressure, not the system relief pressure.
