PE16-S67H Proportional, Pilot Operated (PE16-S67H)

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

Product 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 flow 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 flow direction. The
valve’s spool is symmetrical, providing meter-in and meter-out control.

Product Features

• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
 Good linearity.
