A high pressure, screw-in, cartridge-style, pilot-operated, proportional,
spool-type, hydraulic directional valve.
In neutral (unpiloted), the HPE16-44 blocks flow from 2 to 3. On remote pilot signal at
port 1, the valve's 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 port 4 will
directly (1:1) affect the pilot pressure required and must be added to the spring value.
