Rexroth solenoid valve 4WE6J70/HG24N9K4 R901089241, original from Rexroth

1. Product Overview

This is a product produced byRexrothIt is anindustrial standard solenoid directional valve. It is awet solenoid, spring return/centering typeof2 - position, 4 - wayspool valve, mainly used to control theflow direction and on - off of the hydraulic fluid in the hydraulic system. This valve complies with the ISO 4401 standard (Nominal size NG6 / CETOP 3), and is known for itshigh switching reliability, long service life and wide applicability.

2. Core Features

• High reliability and long service life: It adopts thewet solenoiddesign. The armature works in the hydraulic fluid, effectively improving the cooling and lubrication conditions, significantly reducing wear and extending the service life.

  
  

• Multiple neutral functions: It provides a variety of spool types (such as O, Y, P, J, etc.), and the appropriate oil port connection method can be selected according to different system requirements to adapt to various control logics.

  
  

• Robust structure: The valve body is made of high - strength cast iron or steel, which can withstand high working pressure and frequent impact loads, and is suitable for harsh industrial environments.

  
  

• Convenient installation: It uses the standardSubplate Mountingmethod, which is convenient for installation and replacement on the valve block or manifold block, simplifying the design and maintenance of the hydraulic system.

  
  

3. Typical Applications

• Machine tools: It is used in the hydraulic systems of various machine tools (such as lathes, milling machines, grinders) to control the movement of the workbench and the clamping and loosening of the fixtures.

  
  

• Press machinery: It is used to control the opening and closing, balancing and ejection actions of the molds in equipment such as bending machines and press - fitting machines.

  
  

• Plastic machinery: It is used for the auxiliary action control of small injection molding machines or blow - molding machines.

  
  

• Metallurgical equipment: It is used in the hydraulic auxiliary systems of equipment such as continuous casting machines and rolling mills.

  
  

• General industrial equipment: It is widely used in various automated production lines, testing equipment and special mechanical equipment that require directional control.
