PE12-S67C Valve

U.S. Patent 6,554,014

SYMBOL:
PE12-S67C Valve symbol

DESCRIPTION
A screw-in, cartridge-style, pilot-operated, spring-centered, spool-type,
hydraulic directional valve.

OPERATION
In neutral position, the PE12-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. 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.

FEATURES
• Hardened spool and cage for long life.
• Excellent metering characteristics.
• Good Linearity.
