PE42-S67K Valve

U.S. Patent 6,554,014

SYMBOL:
PE42-S67K Valve symbol

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

OPERATION
In neutral position, the PE42-S67K 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 non-symmetrical, providing meter-in control.

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