Overview

Description

The HPE42-S63 is a high pressure, screw-in, cartridge-style, pilot-operated, normally closed, proportional, spool-type, hydraulic directional valve.

Operation

In neutral position (unpiloted) the spool blocks all flow paths. On remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to gradually opens flow paths from port 2 and 3 and from port 4 to 5 bidirectionally until spool is fully shifted. The spring chamber is vented to port 6. Pressure at port 6 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.
  • 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%.

NOTE: Orifice disc should not be used with this product.
