DIRECTIONAL VALVES
DESCRIPTION
A high-pressure, cartridge-style, pilot-operated, screw-in hydraulic directional valve.
OPERATION
When the HPD42-S67C is in neutral position, all ports are blocked. 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 NFPA
specification T2.6.1.
• All HyPerformance products are tested at a verification level of 90% and an
assurance of 99%.
