Vickers, Danfoss DG4V - 3 - 2AL - M - U - H7 - 69 - EN124 Solenoid valve, Directional control valve,

1. Product Overview

This is a product produced byVickers (now part of Danfoss Power Solutions)It is aWet solenoid directional control valve. This valve belongs to theDG4V - 3 seriesand is aNG6 (CETOP 3 / 6 port size) standard solenoid directional valve, mainly used to control theon - off and flow directionof the hydraulic oil circuit, thereby driving actuators such as cylinders or oil motors to switch the movement direction.

2. Core Features

• Wet solenoid design: It adopts awet solenoidstructure. There is no sealing element between the solenoid push rod and the valve core. The frictional resistance is small, and the wear of the static O - ring seal is eliminated, thus ensuring extremely highoperational reliabilityandultra - long service life.

  
  

• Low noise and low impact: The optimized valve core design results in small pressure impact andlow noiseduring the commutation process, which is beneficial for improving the working environment and protecting system components.

  
  

• Compact structure: TheNG6 (6 port size) specification makes its structure compact and the volume small, which is very suitable for hydraulic systems with limited space.

  
  

• Neutral function: The "2AL" in the model represents theNeutral function (usually theJ - type function). Specifically: when the valve is in the neutral position,port P is connected to port A, port B is closed, and port T is led out separately. This function is often used in occasions that require specific oil circuit configurations.

3. Typical Applications

• Small hydraulic systems: Used for the motion control of equipment such as small presses, test benches, and special automation machines.

  
  

• Lubrication systems: Used to control the switching of the lubricating oil circuit.

  
  

• Cooling systems: Used to control the flow direction of the coolant.

  
  

• Other industrial hydraulic applications: As a standard directional control element, it is widely used in various industrial equipment that requires precise control of the oil circuit direction.
