A high pressures, screw-in, cartridge-style, proportional, spring-centered,pilot-operated spool-type hydraulic directional valve.
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.
• Hardened spool and cage for long life.
