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

OPERATION
In neutral position, the HPD42-S61 allows flow between ports 2 and 3 and between ports 4 and 5.
On remote pilot signal at 1, the valve shifts to allow flow between ports 3 and 4, while blocking
ports 2 and 5.
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.
• 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%.
