DIRECTIONAL VALVES

HPD42-S52 HyPerformance

Piloted 3-Way Spool

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 the 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.

• All HyPerformance™ valves are tested at a verification level of 90%

and an assurance of 99%.
