The DG4V3S8CVMFWH561 valve is manufactured by Vickers within the DG4 Directional Valves series and directs hydraulic flow in automated equipment. A spring-centered spool combined with a tandem center P-to-T path unloads pump flow at neutral to reduce standby losses. The unit withstands 350 bar (5075 psi) at ports P, A, and B, and its flow capacity is 40 l/min (10.5 USgpm). Installation uses the ISO 4401-03 interface, also known as CETOP 3 or NFPA D03, so it fits common subplates. Proper sealing requires a mounting surface that stays within 0.013 mm flatness and 1.1 µm roughness.
Electrically, the solenoid is supplied with flying leads exiting a housing threaded for 1/2 in NPT conduit, and the coil employs Class H windings encased to Class F standards for heat resistance. A 100 % ED duty rating allows continuous energization, while a water-resistant manual override lets operators shift the spool during power loss. Tank port pressure must remain below 100 bar (1450 psi), and fluid cleanliness should meet ISO 4406 19/17/14 to maintain performance. These parameters enable reliable integration of the valve into presses, injection machines, and other hydraulic automation systems.
