DIRECTIONAL VALVES
PE42-S67C Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type
hydraulic directional valve.
OPERATION
When the PE42-S67C is in neutral position all ports are blocked. 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. When the pilot signal at ➅
exceeds the force of the bias spring the spool shifts proportionally to the applied force
to allow fl ow from
➂ to ➁ and from ➃ to ➄. When the pilot signal is less than the force
of the bias spring, the spool will return to the center position. 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.
