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

OPERATION
When in neutral (unpiloted), the HPE42-S50 allows flow between ports 3 and 2 bidirectionally while port 4 is
blocked. On remote pilot signal at 1, the valve’s spool shifts proportionally to the applied pilot pressure to
gradually close ports 3 to 2 while gradually opening ports 3 and 4. The spring chamber is vented to the tank
through port 5. Pressure at port 5 will directly (1:1) affect the pilot pressure required and must be added to
the bias spring value.

FEATURES
• Hardened spool and cage for long life.
• 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%.
