DG4V38CMWLH40S288

The DG4V38CMWLH40S288 valve is manufactured by Vickers within the DG4 Directional Valves series. It directs hydraulic flow in automated circuits that need predictable on-off actuation. The valve uses two wet armature solenoids, so magnetic components are immersed in oil to improve heat dissipation and extend service life. Each solenoid is energized at 24 V DC, allowing direct connection to machine control power without transformers. A continuous 100 % duty cycle supports repeated shifting without cooling pauses. Inside the body, a tandem-center spool designated 8C blocks pump flow while linking cylinder ports to tank in the neutral position, reducing standby energy loss. The spool is spring centered, so hydraulic flow returns to the neutral path automatically after the solenoids are de-energized.

Maximum operating pressure at the P, A, and B ports is 350 bar (5000 psi), enabling use in high-pressure industrial presses or mobile work circuits, while the T port is limited to 207 bar (3000 psi) to protect return-line components. Subplate mounting makes replacement straightforward because the valve lifts off the manifold without disturbing pipework. The mounting interface follows ISO 4401-03, also known as CETOP 3 or NFPA D03, ensuring interchangeability with standard manifolds. The port pattern matches ISO 4401-AB-03-4-A, so flow paths align correctly with the mating subplate cavities. These dimensional features combine with the pressure ratings described earlier to integrate the valve securely into hydraulic automation systems that demand compact size and standardized connections.
