DG4V-5-2CJ/0CJ/3CJ/31CJ/6CJ/7CJ/8CJ/2NJ-M-U-H7 Solenoid directional valve

1. Product Overview

This is a document aboutVickers (now part of Danfoss Power Solutions) DG4V - 5 SeriesList of models of solenoid directional control valves. All valves in this series areWet solenoid directional control valves, adoptingNG10 (CETOP 5 / 10 port size) standard, mainly used to control theon - off and flow direction of the hydraulic oil circuit. Different suffixes in the list (such as 2CJ, 3CJ, etc.) represent differentspool neutral functions andelectrical specifications to meet diverse control requirements.

2. Core Features

• Wet solenoid design: All models usewet solenoids. There is no seal between the push rod and the spool, with low frictional resistance, eliminating the wear of the static O - ring seal, thus ensuringextremely high operational reliability andultra - long service life.

  
  

• Low noise and low impact: The optimized spool structure makes the commutation process smooth,with small pressure impact and low noise, which helps protect system components and improve the working environment.

  
  

• High power density: It provides high flow rate in the size ofNG10 (10 port size), achieving a perfect combination ofsmall volume and large flow rate, suitable for medium - and large - sized hydraulic systems.

  
  

• Diverse neutral functions: Through different spool designs (such as 2CJ, 3CJ, 2NJ, etc.), a variety of neutral functions (such as O - type, Y - type, H - type, P - type, etc.) can be provided to meet the requirements of different working conditions such aslocking of the actuator, system unloading, and floating of the actuator.

  
  

• Standard electrical interface: The suffix “-M - U - H7” represents its electrical specification, usually aflame - proof coil design, suitable forhazardous areas oroccasions with high reliability requirements.

  
  

3. Typical Applications

• Construction machinery: Used for direction control of actions such as walking, slewing, boom, and arm of excavators, loaders, cranes and other equipment.

  
  

• Injection molding machines: Used for controlling actions such as mold opening and closing, ejector pin, and injection of large - scale injection molding machines.

  
  

• Die - casting machines: Used in systems such as injection and mold opening and closing.

  
  

• Metallurgical equipment: Used in the hydraulic systems of heavy machinery such as rolling mills and continuous casting machines.
