The HPE42-S50 is a high pressure, spool type, screw-in, cartridge style, pilot operated, proportional, hydraulic directional valve
In the neutral position (unpiloted) flow is allowed between ports 3 and 2 bidirectionally while port 4 is blocked. On remote pilot signal at port 1 the spool shifts proportionally to the applied pilot pressure to gradually close ports 3 to 2, while gradually opening ports 3 to 4. The spring chamber is vented to the tank through port 5. Pressure at port 5 will directly (1:1) affect the pilot pressure required and must be added to bias spring value
- Hardened spool and cage for long life.
