DIRECTIONAL VALVES
HPE42-M45 HyPerformance
TM
Piloted 2-Way Spool
DESCRIPTION
A high pressure, screw-in, cartridge-style, pilot-operated, proportional spool-type,
hydraulic directional valve.
OPERATION
In neutral (unpiloted), the HPE42-M45 allows flow from 2 to 3 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.
FEATURES
• Hardened spool and cage for long life.
• Optional sealed pilot.
• Cost-effective 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%.
