Rexroth Proportional Valve 4WRZE16W9-150-7X/6EG24N9ETK31/A1D3M 350 Bar Cast Iron Long Service Life Energy-Efficient

Description:

The Rexroth Proportional Valve 4WRZE16W9-150-7X/6EG24N9ETK31/A1D3M is a high-performance electro-hydraulic proportional directional valve manufactured by Bosch Rexroth, a German company. This valve is a spool-type proportional directional valve that employs pilot control technology to achieve precise control of fluid flow direction and flow rate within a hydraulic system. It is an electro-hydraulic proportional directional valve with pilot control functionality. The valve has a bore size of 16 mm, making it suitable for hydraulic systems with medium flow rates. The rated flow rate is 150 L/min, making it suitable for medium-sized hydraulic systems. This valve belongs to the 7X series, which features specific performance characteristics and design features. The electrical connection is a 24V DC power supply, with additional functions such as an electromagnet, plug, and manual operation device, suitable for various control requirements. The valve controls the movement of the pilot valve spool via a proportional electromagnet, thereby driving the main valve spool to achieve continuous regulation of hydraulic fluid flow direction and flow rate. Its core advantage lies in its ability to precisely regulate the movement direction and speed of hydraulic actuators (such as hydraulic cylinders or motors) based on the magnitude of the input electrical signal.

Application Areas:

Industrial Automation: In 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 4WRZE16W9-150-7X/6EG24N9ETK31/A1D3M 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.
Transportation: In the Electronic Brakeforce Distribution (EBD) system of automobiles, the valve automatically adjusts the braking force distribution ratio between the front and rear wheels based on the vehicle's load distribution and driving status, enhancing braking stability and safety. In the rudder hydraulic system of ships, the proportional valve precisely controls the flow direction and volume of hydraulic oil according to the bridge's commands, thereby controlling the rudder blade's rotation angle to achieve precise ship steering.
Construction and Engineering Machinery: In concrete pump trucks, the proportional valve controls the pumping pressure and flow rate of concrete, enabling efficient and precise concrete delivery according to construction requirements. In cranes, the proportional valve precisely controls the pressure and flow rate of the hydraulic system based on the weight of the lifted load and operational requirements, enabling smooth and precise control of boom extension, boom swing, and rotation movements.
Other fields: In robotics, wind power generation, medical equipment, and other fields, this valve is used to control the pressure and flow of the hydraulic system, providing precise power support for various complex movements and operational tasks.

Advantages:

High-precision control: This proportional valve employs electro-hydraulic proportional control technology, enabling continuous, stepless regulation of hydraulic system flow and direction. Compared to traditional on/off directional control valves, it eliminates hydraulic shock and unstable movements, 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 ease of 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.
Multiple Installation Options: Multiple installation methods are available, enabling easy integration into existing hydraulic systems. Its simple design and ease of maintenance reduce downtime and maintenance costs.
