PE12-S67CM

PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE FOR USE WITH MANUAL OPERATOR U.S. PATENT NO. 6,554,014

Overview

Description

The PE12-S67CM is a screw-in, cartridge-style, proportional, spring centered spool, pilot operated hydraulic directional valve for use with a manual operator.

Operation

In neutral position all ports are blocked. 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 the opposite direction, thus reversing the flow directiont. The valve's spool is symmetrical providing meter-in and meter-out control. When used with the manual operator the valve can be operated manually in both directions without pilot pressure.

Features

  • Control function proportionally with pilot signal or operate manually.
  • Hardened spool and cage for long life.
  • Excellent symmetrical (meter-in/meter-out) characteristics.
  • Good Linearity.
