DIRECTIONAL VALVES
PE16-S67K Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot operated spool valve.
OPERATION
When the PE16-S67K is in neutral position, inlet port ➂ is blocked while ports ➁, ➃
and
➄ are connected to each other. With remote pilot signal at port ➀, the valve’s
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 then from
➁ to ➄ and to
tank. Port
➁ is open during transition. On remote pilot signal at ➅, the spool shifts
proportionally to the applied pressure in the opposite direction, reversing the fl ow
direction. Port
➃ is open during transition. The spool is non-symmetrical, providing
only meter-in control.
FEATURES
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
