DIRECTIONAL VALVES
PE12-S67C Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type
hydraulic directional valve.
OPERATION
When the PE12-S67C is in neutral position all ports are blocked. When the remote
pilot signal at
exceeds the force of the bias spring, the spool shifts proportionally
to the applied pilot pressure to allow fl ow from
to through a load such as a
hydraulic cylinder or motor, and from
to and to tank. On remote pilot signal at ,
the valve’s spool shifts proportionally to the applied pressure in the opposite direction,
reversing the fl ow 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.
