DIRECTIONAL VALVES
HPE42-S67C HyPerformance™ Proportional
DESCRIPTION
A high pressures, screw-in, cartridge-style, proportional, spring-centered,
pilot-operated spool-type hydraulic directional valve.
OPERATION
When the HPE42-S67C is in neutral position all ports are blocked. When the remote
pilot signal at 1 exceeds the force of the bias spring, the spool shifts proportionally
to the applied pilot pressure to allow flow from 3 to 4 through a load such as a hydrau-
lic 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 port 6 the
spool shifts proportionally to the applied force in the opposite direction, thus reversing
the flow direction.
The valve’s spool is symmetrical, providing 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 NFPA
specification T2.6.1.
• All HyPerformance™ valves are tested at a verification level of 90% and an
assurance of 99%.
