PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE
Overview
Symbol
Description
The HPE16-45 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 from ports 2 to 3 bi-
directionally. On remote pilot signal at port 1 the spool shifts
proportionally to the applied pilot pressure to gradually close flow path
until spool is fully shifted blocking flow. 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 bias spring value
Features
Hardened spool and cage for long life.
❍
Proportional control.
❍
Industry common cavity.
❍
All HyPerformance products are tested to the rigorous standards of
