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

OPERATION
When the HPE42-M44 is in neutral position (unpiloted), ports 2 and 3 are blocked bidirectionally.
On remote pilot signal at 1, the spool shifts proportionally to the applied pilot pressure to allow
flow from port 2 to 3 bidirectionally. The spring chamber is vented to port 4. Pressure at 4 will
directly (1:1) affect the pilot pressure required and must be added to the bias spring valve.

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 the NFPA
  specification T2.6.1.
• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
