PE42-S67H Proportional, Pilot Operated (PE42-S67H)
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type hydraulic directional valve with neutral position bleed-to-tank.
Product Operation
When the PE42-S67H is in neutral position port ➂ is blocked and ports ➁ and ➃ are connected to ➄. 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 then 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 flow 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 spool is symmetrical and provides meter-in and
meter-out control.
Product Features
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
