PROPORTIONAL, PILOT OPERATED DIRECTIONAL VALVE
Overview
Symbol
Description
The HPE16-44 is a high pressure, screw-in, cartridge-style, pilot-
operated, proportional, spool-type, hydraulic directional valve
Operation
In neutral position (unpiloted) the valve blocks flow from ports 2 to 3. On
remote pilot signal at port 1 the spool shifts proportionally to the applied
pilot pressure to allow flow from port 2 to 3 bi-directionally. 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.
❍
Industry common cavity.
❍
All HyPerformance products are tested to the rigorous standards of
the NFPA specification T2.6.1.
❍
All HyPerformance valves are tested at a verification level of 90%
and an assurance of 99%.
