Rexroth Proportional Valve 4WRZ16W8-100-7X/6EG24N9ETK4/D3V 350 Bar High Precision Control

Description:

The Rexroth 4WRZ16W8-100-7X/6EG24N9ETK4/D3V is a pilot-operated proportional directional control valve that employs electromagnetic proportional control. It primarily consists of a main valve body, pilot valve, proportional solenoid, valve spool, spring-return mechanism, and other components. The valve receives electrical signals via the proportional solenoid to control the action of the pilot valve, thereby adjusting the position of the main spool to achieve continuous regulation of hydraulic oil flow direction and flow rate. The valve has a four-way structure (i.e., it has four main oil ports: P, T, A, and B) and can control the forward and reverse motion of hydraulic actuators. Its control method is electro-hydraulic proportional control, offering high dynamic response performance and control accuracy. 6EG24N9ETK4/D3V: Indicates that the valve is equipped with a 24V DC proportional solenoid valve, featuring an integrated amplifier (OBE), and has specific electrical interfaces and sealing configurations.
 

Application Areas:

The Rexroth 4WRZ16W8-100-7X/6EG24N9ETK4/D3V proportional directional control valve, with its outstanding control performance and reliability, is widely applied across various industrial sectors, particularly in applications requiring high precision and rapid response in hydraulic system control.
Construction Machinery: In construction machinery such as excavators, loaders, bulldozers, and rollers, this proportional valve is used to control the movement of hydraulic cylinders and hydraulic motors, achieving precise speed and direction control. For example, in the control circuits of the boom, stick, and bucket of an excavator, the proportional valve can precisely regulate the flow and direction of hydraulic oil based on signals from the control handle, thereby achieving smooth and efficient motion control.
Injection molding machinery: In plastic injection molding machines, the hydraulic system requires precise control of mold opening/closing, injection, and holding pressure actions. The 4WRZ16W8-100-7X/6EG24N9ETK4/D3V proportional valve enables continuous adjustment of injection speed and pressure, improving the forming accuracy and consistency of products, and is widely used in high-end injection molding equipment.
Metallurgy and heavy machinery: In heavy industrial equipment such as steel mills, smelting plants, rolling mills, and forging equipment, this proportional valve is used to control the movements of large hydraulic cylinders, such as rolling mill roll pressing, shearing, and clamping processes. Its high responsiveness and reliability ensure stable operation of the equipment under harsh conditions such as high pressure and high temperature.
Shipbuilding and Port Equipment: In ship hydraulic systems, port cranes, hatch cover controls, rudder systems, and other equipment, this proportional valve enables remote precise control of hydraulic actuators, enhancing operational safety and efficiency, and is suitable for high-reliability requirements in marine environments.
Testing and Simulation Equipment: In high-precision equipment such as hydraulic test stands, fatigue test machines, and flight simulators, this proportional valve is used to simulate loads and control the movement trajectories of actuators, making it a core component for achieving high-precision control.
 

Advantages:

The Rexroth 4WRZ16W8-100-7X/6EG24N9ETK4/D3V proportional directional valve demonstrates Bosch Rexroth's technical expertise in hydraulic control through its design and manufacturing, offering the following notable advantages:
High-precision control: This valve uses a proportional solenoid for actuation, combined with an internal electronic amplifier (OBE), enabling continuous adjustment of the spool position to achieve precise control of hydraulic oil flow and direction. Its control accuracy far exceeds that of traditional on/off directional control valves, making it suitable for systems requiring high smoothness and repeatability of motion.
Excellent dynamic response performance: This proportional valve features fast dynamic response speed and high frequency response, enabling it to quickly respond to changes in input signals. It is suitable for hydraulic systems requiring high-speed, high-frequency operations. Its response performance approaches that of a servo valve but at a lower cost and with simpler maintenance.
No zero-position dead zone: Traditional hydraulic valves have a control dead zone near the zero position, but this proportional valve achieves zero-position dead zone-free control through optimized spool design and electromagnetic control strategies, enhancing system controllability and stability, particularly suitable for low-speed startup and fine adjustment applications.
Built-in electronic amplifier (OBE): This model is equipped with an integrated electronic amplifier, simplifying system wiring, reducing the number of external control components, and improving the system's interference resistance and reliability. Additionally, the built-in amplifier supports parameter adjustment, allowing optimization based on actual operating conditions.
High reliability and durability: The valve body is made of high-strength cast iron material, with internal components precision-machined and heat-treated, ensuring excellent wear resistance and corrosion resistance. Sealing components are made from high-quality materials to ensure leak-free operation over the long term. The overall design meets industrial-grade standards and is suitable for harsh operating conditions.
Easy Installation and Maintenance: The valve uses a plate-type connection method compliant with ISO 4401 standards, facilitating integration with existing hydraulic systems. Electrical interfaces are standardized for convenient wiring and maintenance. The modular design enables easier replacement and repair, reducing maintenance costs and downtime.
