Name:Proportional Flow Control Valve (Rexroth - BOSCH). - 2-Way Proportional Throttle Valve Type 2FRE. - Nominal Size 6. - Porting Pattern To DIN 24340 Form A. - B : Without External Closing Of The Pressure Compensator. - 25Q - Progressive : up to 25L/min . -
Description:The Bosch Rexroth valve that matches your specified configuration is the 2FRE 6B-2X/25QK4MV. This is a 2-way proportional throttle valve with a progressive flow characteristic up to 25 L/min, without the external closing feature on the pressure compensator, and without an internal check valve . ✅ Valve Specifications Parameter Specification for 2FRE 6B-2X/25QK4MV Model 2FRE 6B-2X/25QK4MV Valve Type 2-way proportional flow control valve Nominal Size 6 (NG6) Component Series 2X Pressure Compensator B – Without external closing (standard) Flow Characteristic 25Q – Progressive, up to 25 L/min Max. Operating Pressure 210 bar Electrical Connection K4 – Individual connection, without mating connector (DIN EN 175301-803) Check Valve M – Without check valve Seal Material V – FKM (fluororubber) Material Number R900937870 🔧 Understanding the Ordering Code The type code breaks down as follows : 2FRE: 2-way proportional flow control valve. 6: Nominal size 6. B: Without external closing of the pressure compensator (as specified). 2X: Component series 20 to 29 (dimensions remain unchanged). 25Q: Progressive characteristic, max flow 25 L/min (as specified). K4: Electrical connection with component plug (without mating connector). M: Without check valve. V: FKM seals. 💡 Key Design Features This valve uses a proportional solenoid and an inductive position transducer to provide closed-loop position control of the metering orifice, ensuring the flow rate is maintained independently of load pressure changes . It is designed for subplate mounting to ISO 4401-03-02-0-05 and requires an external amplifier (e.g., Rexroth VT-VRPA1 series) for operation . As this version (B) has no check valve ("M" suffix), flow is controlled only in the A→B direction. Reverse flow from B→A is blocked .
