HPE16-45

PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE

Overview

Description

The HPE16-45 is a high pressure, screw-in, cartridge-style, pilot-operated, proportional, spool-type, hydraulic directional valve

Operation

In neutral position (unpiloted) the valve allows flow from ports 2 to 3 bi-directionally. On remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to gradually close flow path until spool is fully shifted blocking flow. The spring chamber is vented to port 4. Pressure at port 4 will directly (1:1) affect the pilot pressure required and must be added to bias spring value

Features

  • Hardened spool and cage for long life.
  • Proportional control.
  • Industry common cavity.
  • All HyPerformance products are tested to the rigorous standards of the NFPA specification T2.6.1.
  • All HyPerformance valves are tested at a verification level of 90% and an assurance of 99%.
