PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE
Overview
Symbol
Description
The HPE42-S62 is a high pressure, screw-in, cartridge-style, pilot-
operated, proportional, spool-type, hydraulic directional valve
Operation
In neutral position (unpiloted) the valve allows flow between ports 2 and
3 and between ports 4 and 5 bidirectionally. On remote pilot signal at
port 1 the spool shifts proportionally to the applied pilot pressure to
gradually close flow paths until spool is fully shifted blocking all ports.
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.
❍
