HPE42-M45 Valve

HPE42-M45 Valve symbol

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

When the HPE42-M45 is in neutral position (unpiloted), ports 2 and 3 allows flow bidirectionally.
On remote pilot signal at 1, the spool shifts proportionally to the applied pilot pressure to gradually
close the flow path until the spool is fully shifted, blocking flow. 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.

• 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
• All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
