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 SpecificationsParameter Specification for 2FRE 6B-2X/25QK4MVModel 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 CodeThe 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 FeaturesThis 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 .
