DESCRIPTION
A high-pressure, screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic directional valve.
OPERATION
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.
FEATURES
• Hardened spool and cage for long life.
• Flows up to 379 lpm/100 gpm.
• 1000 hour salt spray tested.
• Vibration tested (3-axis) to 20G RMS.
• All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.
• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%
