DIRECTIONAL VALVES
PE42-S67H Proportional, Pilot Operated
DESCRIPTION
A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type
hydraulic directional valve with neutral position bleed-to-tank.
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 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. 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 spool is symmetrical and provides meter-in and
meter-out control.
FEATURES
• Hardened spool and cage for long life.
• Cost-effective cavity.
• Excellent metering characteristics.
• Good linearity.
