PE42-S67D Valve

U.S. Patent 6,554,014

SYMBOL:
PE42-S67D Valve symbol

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

OPERATION
In neutral position, the PE42-S67D blocks port 3 while 2, 4 and 5 are connected to each
other. When the remote pilot signal at 1 exceeds the force of the bias spring, the spool
shifts proportionally to the applied pilot pressure to allow flow from 3 to 4 through a load
such as a hydraulic cylinder or motor, and from 2 to 5 and to tank. On remote pilot signal
at 6, the valve’s spool shifts proportionally to the applied pressure in the opposite direction,
reversing the flow direction. The valve’s spool is symmetrical, providing meter-in and
meter-out control.

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