U.S. Patent 6,554,014
A high pressure, screw-in, cartridge-style, pilot-operated, spring-centered, spool-type,
hydraulic directional valve.
In neutral position, the HPE42-S67C blocks all ports. 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 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 valve’s spool shifts proportionally to the applied pressure in the opposite direction, reversing the flow direction. The valve’s spool is symmetrical, providing meter-in and meter-out control.
• 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%.
