PROPORTIONAL, PILOTED OPERATED DIRECTIONAL VALVE
Overview
Symbol
Description
The HPE42-S50 is a high pressure, spool type, screw-in, cartridge style,
pilot operated, proportional, hydraulic directional valve
Operation
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
Features
Hardened spool and cage for long life.
