PE16-S67K

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

Overview

Description

The PE16-S67K is a screw-in, cartridge style, proportional, spring centered spool, 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 (port 2 is open during transition). 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 (port 4 is open during transition). The valve's spool is non-symmetrical providing only meter-in control.

Features

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