A high-pressure, screw-in, cartridge-style, pilot-operated, 4-way, spool-type, hydraulic directional valve.
When the HPD16-S67C is in neutral position, all ports are blocked. When remote pilot signal at 1, exceeds force of bias spring, the spool shifts to allow flow from 3 to 4 and from 2 to 5. When remote pilot signal at 6 exceeds force of bias spring, the spool shifts to allow flow from 3 to 2 and from 4 to 5.
• Hardened spool and cage for long life.
• 110 and 170 psi bias springs available.
• 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%.
