Rexroth Proportional Valve 4WRAE10E60-2X/G24N9K31/A1V 315 Bar High Safety High-Temperature Fully Modular Design

Description:

Rexroth 4WRAE10E60-2X/G24N9K31/A1V (Part Number R900558356) is a direct-acting three-position four-way proportional directional valve from the 4WRAE series by Bosch Rexroth, with a nominal diameter of NG10 and a component series of 2X. It employs a proportional solenoid to directly drive a spring-centered control spool. The valve body is mounted on an ISO 4401 base plate, with port configurations offering high interchangeability; It integrates an OBE electronic amplifier (On-Board Electronics) internally, powered by 24 V DC, with a control signal of ±10 V (A1 type), enabling continuous and linear regulation of flow rate and direction without the need for an external amplifier board. The valve has a maximum operating pressure of 315 bar, a rated flow rate of 75 l/min, low hysteresis, and fast response, making it suitable for industrial hydraulic systems with high requirements for dynamic performance and repeatability.
 

Application areas:

Metal forming machine tools: Slider position, speed, and clamping force control for bending, shearing, stamping, and hydraulic servo presses
Plastic and rubber machinery: Mold opening/closing, injection, holding pressure, and barrel temperature control integrated hydraulic circuits for injection molding machines
Mobile and lifting equipment: Proportional multi-way valve pilot stage for automotive crane boom extension, concrete pump truck boom, and aerial work platform
Testing and simulation: Multi-channel coordinated loading systems for fatigue test stands of automotive chassis and aerospace structural components
Die-casting, forging, and extrusion production lines: Synchronized control of extrusion cylinder speed and ejection mechanisms
Wind power and solar tracking: Pitch angle, yaw braking, and hydraulic servo units for photovoltaic mounting structures
Shipbuilding and marine engineering: Electro-hydraulic proportional control of rudder actuators, winches, and heave compensation devices
Steel rolling and metallurgy: hydraulic roll-down for strip rolling mills, vibration servo circuits for continuous casting machine crystallizers
Packaging and papermaking: hydraulic systems for tension control, alignment, and cutting positioning in high-speed corrugated paper production lines
Robotics and special automation: joints for heavy-duty handling robotic arms, electro-hydraulic hybrid drive units
 

Advantages:

Integrated OBE, simplified wiring, eliminates external amplifiers and complex shielded cables, reduces commissioning and fault points
Direct-acting structure, no pilot leakage, low energy consumption at zero flow, slow oil temperature rise
Spring-centered and proportional solenoid closed-loop force feedback, hysteresis < 1%, high repeatability, improves product consistency
Selectable valve spool coverage to accommodate different system stiffness requirements, balancing stability and sensitivity
Fully modular design for 6-way and 10-way valve bodies, coils, and electronic boards, with interchangeable spare parts and low maintenance costs
ISO 4401 mounting surface, compatible with NG6 and NG10 directional valves and stacked valves, no need to modify the oil block for system upgrades
350 bar pressure rating design, high safety factor, capable of withstanding pressure peaks and shock loads

FKM seals, compatible with mineral oil, water-glycol, and biodegradable hydraulic oil, suitable for high-temperature, high-humidity, and salt fog environments
24 V vehicle power supply and industrial-grade ±10 V interface, directly compatible with PLCs, motion controllers, and CNC systems
Factory-preset, no adjustment required; only zero point and gain need to be set on-site, shortening equipment commissioning time
Strong contamination resistance, valve core/body with hard chrome plating, capable of long-term reliable operation with NAS 9-grade oil, reducing filtration costs
Low-power proportional coil with continuous operating temperature rise < 50 K, saving energy and extending coil insulation lifespan
High dynamic response (step response within 30 ms), meeting closed-loop position, pressure, and speed control requirements with a bandwidth of 20 Hz or less
Global service network and long-term spare parts support, ensuring controllable equipment lifecycle costs and reducing downtime risks
