HPE16-S67C

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

Overview

Description

The HPE16-S67C is a high pressure, screw-in, cartridge-style, proportional, spring-centered spool, pilot-operated, hydraulic directional valve.

Operation

In neutral position all ports are blocked. on remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to allow flow from port 3 to 4, thru a load such as a hydraulic cylinder or motor, and from port 2 to 5 and to tank. Port 5 is to be used as tank port only with maximum pressure of 69 bar (1000 psi). On remote pilot signal at port 6 the spool shifts proportionally to the applied force in the opposite direction, thus reversing the flow direction. The spool is symmetrical and provides meter-in and meter-out control.

Features

  • Hardened spool and cage for long life.
  • Cost-effective cavity.
  • Excellent metering characteristics.
  • Good Linearity.
  • All HyPerformance™ products are tested to the rigorous standards of the NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
