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.
In neutral (unpiloted), the HPD42-M45 blocks 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.
Port 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.
• 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 the NFPA specification T2.6.1.
• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
