DIRECTIONAL VALVES
PE16-S67H Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type
hydraulic directional valve.
OPERATION
When the PE16-S67H is in neutral position port ➂ is blocked and ports ➁, ➃ and ➄
are in communication with 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 spool shifts proportionally to
the applied pressure in the opposite direction, thus 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.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
