DIRECTIONAL VALVES
HPE16-S67K HyPerformance™ Proportional
DESCRIPTION
A high pressure, screw-in, cartridge-style, proportional, spring-centered spool, pilot
operated hydraulic directional valve.
OPERATION
When the HPE16-S67K is in neutral position, inlet port 3 is blocked while ports 2, 4
and 5 are connected to each other. On remote pilot signal at port 1, the valve’s 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 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 pressure in the
opposite direction, reversing the flow direction.
The spool is non-symmetrical, providing only meter-in 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%.
