DIRECTIONAL VALVES
DESCRIPTION
A high pressure, screw-in, cartridge-style, pilot-operated, spool-type, hydraulic
cartridge valve.
OPERATION
In the neutral position, the HPD42-S63 blocks flow at all ports. On remote pilot signal
at 1, the valve shifts to allow flow between ports 2 and 3, and between 4 and 5
bidirectionally. 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 increase the 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%
