DIRECTIONAL VALVES
HPD42-M45 HyPerformance
TM
Piloted 2-Way Spool
DESCRIPTION
A high performance, screw-in, cartridge-style, pilot-operated, spool-type, hydraulic
directional valve for two-way circuits requiring remote pilot actuation and vented
spring chamber.
OPERATION
In neutral (unpiloted), the HPD42-M45 allows flow from 3 to 2 bidirectionally.
The spring chamber is directed to port 4.
On remote pilot signal at 1, the valve shifts to block 3 to 2 bidirectionally.
Note that 4 is common to the spring chamber. Pressure on 4 will directly (1:1) affect
required pilot pressure and must always be added to the bias spring value.
FEATURES
• Multiple function/application potential.
• Smooth shift transition.
• Low pressure drop.
• Hardened spool and cage for long life.
• Optional sealed pilot.
• Industry-standard ISO cavity.
• All HyPerformance products are tested to the rigorous standards of NFPA
specification T2.6.1.
• All HyPerformance products are tested at a verification level of 90% and an
assurance of 99%.
