PE16-S67K Proportional, Pilot Operated (PE16-S67K)
A screw-in, cartridge-style, proportional, spring-centered, pilot operated spool valve.
Product 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 flow 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 flow
direction. Port ➃ is open during transition. The spool is non-symmetrical, providing only meter-in control.
Product Features
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
