DIRECTIONAL VALVES

PE16-S67C Proportional, Pilot Operated

DESCRIPTION

A screw-in, cartridge-style, proportional, spring-centered, pilot-operated spool-type

hydraulic directional valve.

OPERATION

When the PE16-S67C is in neutral position all ports are blocked. 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 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 valve’s spool is

symmetrical, providing meter-in and meter-out control.

FEATURES

• Hardened spool and cage for long life.

• Cost-effective cavity.

• Excellent metering characteristics.

• Good linearity.
