A proportional, pilot-operated, screw-in, cartridge-style, spool-type, hydraulic directional valve for
use in high pressure applications.
When in neutral, the HPE42-S51 allows flow between ports 2, 3 and 4. On remote pilot signal at 1, the valve’s
spool shifts proportionally to the applied pilot pressure to gradually close flow paths until the spool is fully shifted,
blocking all ports. The spring chamber is vented to the tank through port 5. Pressure at port 5 will directly (1:1)
affect the pilot pressure required and must be added to the bias spring value.
