PE12-S67D Valve

U.S. Patent 6,554,014

SYMBOL:
PE12-S67D Valve symbol

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

OPERATION
In neutral position, the PE12-S67D blocks port 3 while 2, 4 and 5 are connected to
each other. 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.
