DIRECTIONAL VALVES
PE12-S67D Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type
hydraulic directional valve.
OPERATION
When the PE12-S67D is in neutral position, port ➂ is blocked while ➁, ➃ and ➄ are
connected to each other. When the remote pilot signal at
➀ exceeds the force of the
bias spring, the spool shifts proportionally to the applied pilot pressure to allow fl ow
from
➂ to ➃ through a load such as a hydraulic cylinder or motor, and from ➁ to ➄
and to tank. On remote pilot signal at
➅, 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 parts for long life.
• Excellent metering characteristics.
• Good linearity.
