A high-pressure, screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic directional
When the HPD42-S67D is in neutral position, port 3 is blocked and flow is allowed between ports
2, 4, and 5. When remote pilot signal at 1 exceeds force of bias spring, the spool shifts to allow
flow from 3 to 4 and from 2 to 5. When remote pilot signal at 6 exceeds force of bias spring, the
spool shifts to allow flow from 3 to 2 and from 4 to 5.
