Rexroth Proportional Valve 4WRPH6C3B40L-2X/G24K0/M-750 Cast Iron High Reliability High-Precision Control

Description:

The Rexroth Proportional Valve 4WRPH6C3B40L-2X/G24K0/M-750 is a high-performance proportional directional valve manufactured by Bosch Rexroth in Germany, widely used in applications requiring precise control of hydraulic system flow and direction. This valve is a pilot-operated proportional directional valve that uses an electrical signal to control the movement of the pilot spool, thereby driving the main spool to achieve continuous regulation of hydraulic oil flow direction and flow rate. This valve is a proportional directional valve with pilot control. The valve has a bore size of 6 mm and a rated flow rate of 40 L/min. This valve belongs to the second-generation design. The electrical connection is a 24V DC power supply with an electromagnet. The valve includes electrical position feedback (LVDT) for precise control of the spool position. The valve uses a pilot-controlled structure, where the proportional electromagnet receives a voltage signal to generate the corresponding action, causing the working valve spool to move and the valve orifice size to change, thereby achieving pressure and flow output proportional to the input voltage.
 

Application areas:

Industrial automation: In modern industrial automation systems, hydraulic actuators require high-precision control. This proportional valve can be used to control the displacement, speed, and force of hydraulic cylinders, enabling programmable control of complex movements. For example, in automated assembly lines, stamping equipment, injection molding machines, and other systems, the 4WRPH6C3B40L-2X/G24K0/M-750 ensures smooth operation and rapid response.
Construction Machinery: In construction equipment such as excavators, cranes, and concrete pump trucks, this valve is used to control the movements of hydraulic motors and cylinders, enabling precise operations. For example, in crane boom extension control, the proportional valve can precisely control the extension speed of the cylinder based on input signals from the control lever, enhancing operational safety and efficiency.
Metallurgy and heavy machinery: In heavy equipment such as steel mills, rolling mills, and presses, this proportional valve can be used to control high-pressure hydraulic systems, enabling precise control of heavy-duty equipment. Its high pressure resistance and stability make it suitable for extreme operating conditions.
Testing and Simulation Equipment: In systems with high dynamic response requirements, such as hydraulic test stands, flight simulators, and automotive testing equipment, this valve provides high-frequency, high-precision hydraulic control to meet complex testing needs.
 

Advantages:

High-Precision Control: This proportional valve employs electro-hydraulic proportional control technology to achieve continuous, stepless regulation of hydraulic system flow and direction. Compared to traditional on/off directional control valves, it avoids hydraulic shock and unstable operation, significantly improving system control precision and stability.
Fast Response Speed: Due to its pilot-controlled structure, this valve has a fast response speed, making it suitable for applications requiring frequent start/stop operations or rapid directional changes. Its dynamic response characteristics meet high-frequency control requirements, enhancing overall system efficiency.
Energy-efficient and high-performance: By precisely controlling oil flow, the valve minimizes unnecessary energy loss. For example, in low-load conditions, the system automatically reduces flow output to minimize energy waste, enabling energy-efficient operation.
High reliability: Rexroth proportional valves are constructed using high-quality materials and advanced manufacturing processes, offering excellent wear resistance and contamination resistance. Their rational structural design ensures easy maintenance, a long service life, and suitability for long-term continuous operation.
Compatibility and Modularity: This valve can be seamlessly integrated with Rexroth amplifiers, sensors, controllers, and other components to build a complete electro-hydraulic proportional control system. Its modular design facilitates system expansion and maintenance.
Electrical Position Feedback: This valve is equipped with electrical position feedback (LVDT), enabling real-time monitoring of the valve spool position to ensure control accuracy. This feedback mechanism enables more precise control of the valve spool position, further improving system reliability and stability.
