R901218100 3DREME16P-7X/200YG24K31/F1V German Rexroth proportional pressure reducing valve

Detailed Model Code Breakdown

The full model code 3DREME16P-7X/200YG24K31F1Vspecifies the key configuration:

• 3DREME: Series designation.

  • 3DRE: 3-way Proportional Pressure Reducing Valve.

  • M: Maximum Pressure Limitation​ (Mechanical safety valve to prevent overpressure at port A).

  • E: On-Board Electronics (OBE).

• 16: Size NG16.

• P: Subplate mounting.

• 7X: Component series (70-79).

• 200: The maximum electrically adjustable pressure is 200 bar.​ (Note: The valve body is rated for 315 bar, but the setting is limited to 200 bar).

• YG24: Y​ = Internal pilot supply (from P), external drain (to Y); G24​ = 24V DC supply.

• K31: 7-pin electrical connector.

• F1: Command input is a 4 ~ 20 mA current signal.

• V: Seal material is FKM (Viton).

Key Selection and Application Notes

1. Pilot Drain (Port Y) is Critical:​ The Y​ version uses internal pilot supply (from port P), but Port Y must be connected directly to tank with zero backpressure. Any backpressure on Y will cause erratic valve operation and pressure instability.

2. Pressure Setting Limit:​ While the valve body is rated for 315 bar, this specific variant is electronically limited to a maximum setting of 200 bar. For higher adjustable pressures, select a model with code "250" or "315".

3. Integrated Amplifier (OBE):​ The E​ in the code signifies On-Board Electronics. No external amplifier card is required. Connect 24V DC power and the 4-20 mA command signal directly to the valve's connector.

4. Mechanical Safety (M):​ The M​ code indicates the valve includes a mechanical maximum pressure limitation (a small safety relief valve). This provides hydraulic protection in case of an electrical fault (e.g., excessive input signal).
