Rexroth H-4WEH25J6X Proportional Valve, 350 Bar, 650 L/min, Cast Iron

Description:

The Rexroth Proportional Valve H-4WEH25J6X/6EG24N9ETK4/B10D3 is a high-performance industrial hydraulic proportional directional valve manufactured by Bosch Rexroth, a German company. The valve employs electromagnetic drive technology, enabling precise control of the current through the electromagnetic coil to achieve continuous regulation of hydraulic oil flow direction and volume. It features high precision, rapid response, and high reliability, making it suitable for a wide range of industrial applications.

Maximum operating pressure: 350 bar. Maximum flow rate: 650 L/min. Electromagnetic drive, proportional control.

Application areas:

Industrial automation: This proportional valve is widely used in industrial automation applications, such as in injection molding machines, hydraulic presses, and automated assembly lines, to precisely control the direction and speed of hydraulic cylinders and motors. Its high precision and rapid response capabilities significantly enhance production efficiency and product quality.

Construction machinery: In construction machinery such as excavators, cranes, and loaders, this valve is used to control the direction and flow rate of oil in the hydraulic system, enabling precise operation of the equipment. For example, in the boom control of a crane, the proportional valve can precisely control the extension and retraction 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 withstand high pressure and large flow rates, ensuring stable operation of the equipment under extreme conditions. Its high pressure resistance and durability make it an ideal choice for hydraulic systems in heavy machinery.

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 valve uses proportional control technology to precisely regulate the flow and direction of hydraulic oil based on the magnitude of the input electrical signal. Compared to traditional on/off directional valves, it avoids hydraulic shock and unstable operation, significantly improving system control precision and stability.

Fast Response: Due to its electromagnetic drive structure, the valve has a fast response speed, making it suitable for applications requiring frequent start/stop operations or rapid directional switching. Its dynamic response characteristics meet high-frequency control requirements, enhancing overall system efficiency.

Energy-Efficient and High-Performance: By precisely controlling fluid flow, the valve minimizes unnecessary energy loss. For example, in low-load conditions, the system automatically reduces flow output to reduce energy waste, enabling energy-efficient operation.

High reliability and durability: Rexroth proportional valves are made of 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. Additionally, its modular design facilitates system expansion and maintenance.
