HPD12-S67C Valve

SYMBOL: HPD12-S67C Valve symbol

 

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spool-type, hydraulic directional valve for use
in high pressure applications. NOTE: Adapter lock kit (P/N 4209290) may be required when
pilot pressure exceeds 35 bar (500 psi).

OPERATION
When the HPD12-S67C is in neutral position, all ports are blocked. When remote pilot
signal at 1 exceeds the force of the bias spring, the valve shifts to allow flow from 3 to 4
and from 2 to 5. When remote pilot signal at 6 exceeds the force of the bias spring, the
valve shifts to allow flow from 3 to 2 and from 4 to 5.

FEATURES
• High pressure operation.
• Hardened spool and cage for long life.
• Cylinder spool with sealed spool option available.
• All HyPerformance™ products are tested to the NFPA specification T2.6.1 at a
   verification level of 90% and an assurance of 99%..
