DIRECTIONAL VALVES
HPE42-S67K HyPerformance™ Proportional,
DESCRIPTION
A high pressure, screw-in, cartridge-style, proportional, spring-centered, pilot-operat-
ed spool-type hydraulic directional valve.
OPERATION
When the HPE42-S67K is in neutral position port 3 is blocked and ports 2, 4 and 5
are connected to each other. On remote pilot signal at 1, the spool shifts proportion-
ally to the applied pilot pressure to allow flow from 3 to 4 through a load such as a
hydraulic cylinder or motor and from 2 to 5, and to tank. Port 5 is to be used as a tank
port only with maximum pressure of 69 bar (1000 psi). On remote pilot signal at 6, the
spool shifts proportionally to the applied force in the opposite direction, thus reversing
the flow direction.
The spool is non-symmetrical, providing only meter-in control.
FEATURES
• Hardened spool and cage for long life.
• 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%.
