DIRECTIONAL VALVES
HPE42-M44 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-M44 blocks flow from 2 to 3 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
• 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%.
