4WE10J50/HG24N9K4/M R901278744 Solenoid Directional Valve for Rexroth

1. Basic Introduction

-4WE10J50/HG24N9K4/M is a high-performance electromagnetic directional valve. It plays a key role in hydraulic control systems, mainly used to control the flow of hydraulic oil, thereby achieving control over the direction of movement of hydraulic actuators such as hydraulic cylinders and hydraulic motors.

2. Working principle related

-In terms of working principle, the internal electromagnet generates a magnetic field when powered on. For this electromagnetic directional valve, when a rated DC 24V voltage (represented by HG24) is applied, the electromagnetic force generated by the electromagnet is sufficient to drive the valve core to move. The "J" represents a specific valve core function, which determines the connectivity of each oil port of the valve in different working states, thereby achieving precise control of the hydraulic oil flow direction. For example, in a certain working state, it can connect the pressure oil port with one working oil port and the return oil port with another working oil port to push the hydraulic cylinder to extend or retract.

3. In terms of special functions

-It is equipped with a manual emergency operation device (N9). This is a very important function, in case of electrical system failure (such as electromagnetic damage or power outage), the operator can manually change the position of the valve core. This emergency operation device also has protective measures to ensure that the valve will not be damaged during manual operation, and it can also maintain a certain working ability of the hydraulic system in emergency situations, providing a guarantee for the safe and stable operation of the system.

4. Installation and compatibility

-In terms of installation, the installation dimensions of the valve comply with the corresponding standards, and the number "50" is also related to installation specifications, making it very convenient to install into hydraulic systems without the need for special modifications to the connection parts of the system. Its electrical connection adopts component plugs (K4) that comply with DIN EN 175301-803 standard, which ensures good compatibility with other electrical equipment. When constructing complex hydraulic electrical control systems, it can be easily connected to other control components, reducing problems caused by incompatible electrical connections.

5. Industrial application field

-In industrial applications, this type of electromagnetic directional valve is widely used. In the machine tool industry, it can be used to control the feed direction and speed of the worktable; In injection molding machines, it can accurately control the opening and closing actions of injection molds and injection pressure; In the field of construction machinery, such as the motion control of the boom, arm, and bucket of excavators, as well as the loading and unloading motion control of loaders, all rely on this electromagnetic directional valve.
