Product Description:
The Bosch Rexroth 2FRM 6 K2-1X/32QRV (R900572182) is a premium screw-in cartridge valve engineered for precise flow regulation and pressure compensation in hydraulic applications. As part of the FRM.K product family, this 3-way flow regulator ensures stable flow rates regardless of pressure or temperature fluctuations, making it ideal for industrial, mobile, and construction machinery.
Key Features & Design:
- Precision Control: Equipped with an internal hexagon grub screw for easy adjustment of throttle cross-sections, enabling customizable flow settings.
- Pressure Compensation: Integral pressure compensator maintains consistent flow by balancing upstream/downstream pressures, optimizing system efficiency.
- Reverse Flow Check: Allows free return flow from port B to A via a built-in check valve, enhancing operational flexibility.
- Robust Construction: FKM-sealed design resists corrosion from hydraulic fluids (HL, HLP, HEES, HEPG) and ensures long-term durability.
Technical Advantages:
- High Performance: Handles max pressure up to 315 bar and flow rates up to 40 L/min, suitable for high-demand systems.
- Pilot-Operated Spool: Reliable operation with a normally open position for immediate system readiness.
- Compact & Lightweight: Weighs just 0.19 kg for space-saving installation in confined hydraulic setups.
Applications:
- Industrial Machinery: Presses, injection molding, and metalworking equipment.
- Mobile Hydraulics: Agricultural tractors, forklifts, and forestry machinery.
- Construction Equipment: Excavators, cranes, and concrete pumps.
