DIRECTIONAL VALVES
HPE42-S67H HyPerformance™ Proportional,
DESCRIPTION
A high pressure, screw-in, cartridge-style, proportional, spring-centered, pilot-operat-
ed spool-type hydraulic directional valve with neutral position bleed-to-tank.
OPERATION
When the HPE42-S67H is in neutral position inlet port 3 is blocked and ports 2, 4,
and 5 are communicating with each other. On remote pilot signal at 1 the spool shifts
proportionally to the applied pilot pressure to allow flow from 3 to 4 through a load
such as a hydraulic cylinder or motor, and then from 2 to 5, and to tank. Port 5 is to
be used as tank port only with maximum pressure of 69 bar (1000 psi). On remote
pilot signal at port 6, the spool shifts proportionally to the applied force in the opposite
direction, thus reversing the flow direction.
The spool is symmetrical and provides meter-in and meter-out control.
FEATURES
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
• All HyPerformance™ products are tested to the rigorous standards of the NFPA
specification T2.6.1 and are tested at a verification level of 90% and an assurance
of 99%.
