PE42-S67D

PROPORTIONAL, PILOT OPERATED, SPRING CENTERED SPOOL DIRECTIONAL VALVE U.S. PATENT NO. 6,554,014

Overview

Description

The PE42-S67D is a screw-in, cartridge-style, proportional, spring centered spool type, pilot operated hydraulic directional valve.

Operation

In neutral position inlet port 3 is blocked and ports 2, 4 and 5 are communicating with each other. On remote pilot signal at port 1 the valve's spool shifts proportionally to the applied pilot pressure to allow flow from port 3 to port 4, thru a load, such as hydraulic cylinder or motor, and then from port 2 to port 5 and to tank. On remote pilot signal at port 6 the valve's spool shifts proportionally to the applied pressure in opposite direction thus 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.
