HPD42-S51 Valve

SYMBOL:
HPD42-S51 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for use in high
pressure applications.

OPERATION
When in neutral the HPD42-S52 blocks flow between all ports. On remote pilot signal at 1, the
valve's spool shifts to allow flow between ports 2, 3, and 4. The spring chamber is vented to the
tank through port 5. The vented spring chamber allows the valve to be fully pressurized at ports 1,
2, 3, and 4 without affecting required pilot pressure. Pressure at port 5 will increase ther required
pilot pressure at a 1:1 ratio.

FEATURES
• Hardened spool and cage for long life.
• All HyPerformance™ products are tested to the rigorous standards of the NFPA specification
  T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
