PROPORTIONAL, PILOTED OPERATED DIRECTIONAL VALVE
Overview
Symbol
Description
The HPE42-S51 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 2, 3 and
4. 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 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.
❍
All HyPerformance products are tested to the rigorous standards of
the NFPA specification T2.6.1.
❍
