HPD42-S62 Valve

SYMBOL:
HPD42-S62 Valve symbol

DESCRIPTION
A high pressure, screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic
directional valve.

OPERATION
In neutral position, the HPD42-S62 allows flow between ports 2 and 3 and between ports 4 and 5.
On remote pilot signal at 1, the valve shifts to block flow at all ports.
The spring chamber is vented to the tank through port 6. The vented spring chamber allows the
valve to be fully pressurized at ports 1, 2, 3, 4 and 5 without affecting required pilot pressure.
Pressure at 6 will affect required pilot pressure at a 1:1 ratio.

FEATURES
• Hardened spool and cage for long life.
• Optional sealed spool between ports 1 and 2.
• 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%.
