Product Features
• Accurate proportional flow control with pressure compensation – ensures consistent flow regardless of load pressure.
• High flow capacity for size 6 valve up to ~250 L/min – ideal for heavy marine hydraulics.
• Modular stackable control section design allows flexible build-out of hydraulic manifolds.
• Solenoid drive with enlarged spool and metering orifice for precise fine control.
• Robust German build quality – designed for marine, offshore and industrial environments.
• Subplate mounting with standardized pattern permits easy retrofit and system integration.
• Load-compensated metering ensures minimal drift and outstanding repeatability (<1% at qVmax) on appropriate models.
Applications
• Marine hydraulic control systems – deck machinery, crane hydraulics, valve control.
• Offshore platform hydraulic manifolds and high-flow hydraulic actuators.
• Industrial mobile hydraulics – large excavators, drilling rigs, heavy lifting equipment.
• Process automation – hydraulics in power plants, refineries, metals and manufacturing plants.
• Ship repair and retrofit projects – replacing older valves with high-precision proportional units.
Marine & Offshore Advantages
The Rexroth 2FRE 6B-22/250K4MV delivers the precision, durability and flow capacity essential in maritime and offshore hydraulic systems. Built to withstand vibration, salt environment, and high duty cycles, it suits shipboard manifold systems and offshore hydraulics that require accurate flow control under dynamic conditions.
