HPE16-44

PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE

Overview

Description

The HPE16-44 is a high pressure, screw-in, cartridge-style, pilot-operated, proportional, spool-type, hydraulic directional valve

Operation

In neutral position (unpiloted) the valve blocks flow from ports 2 to 3. On remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to allow flow from port 2 to 3 bi-directionally. 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.
  • 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%.
