HPD16-44 Valve

HPD16-44 Valve symbol

A high pressure, screw-in, cartridge-style, piloted, spool-type, 2-way hydraulic
directional valve with remote pilot actuation.

In neutral (unpiloted), the HPD16-44 blocks flow from 2 to 3. On remote pilot signal at port 1,
the valve's spool shifts to allow flow from ports 2 to 3 bidirectionally.
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 the bias spring value.

• Hardened spool and cage for long life.
• Optional sealed pilot.
• 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%.
