A high-pressure, screw-in, cartridge-style, pilot-operated, proportional spool-type, hydraulic
When the HPE42-M44 is in neutral position (unpiloted), ports 2 and 3 are blocked bidirectionally.
On remote pilot signal at 1, the spool shifts proportionally to the applied pilot pressure to allow
flow from port 2 to 3 bidirectionally. The spring chamber is vented to port 4. Pressure at 4 will
directly (1:1) affect the pilot pressure required and must be added to the bias spring valve.
• Multiple function/application potential.
