PILOTED DIRECTIONAL VALVE
Overview

Description
The HPD16-S50X is a high pressure, spool type, screw-in, cartridge
style, pilot operated, hydraulic directional valve
Operation
In the neutral position flow is allowed between ports 3 and 2
bidirectionally while port 4 is blocked. On remote pilot signal at port 1 the
valve's spool shifts to block port 2 while opening flow between ports 3
and 4 bidirectionally. The spring chamber is vented to the tank through
port 5. The vented spring chamber allows the valve to be fully
pressurized at ports 1, 2, 3 and 4 without affecting required pilot
pressure. Pressure at port 5 will increase the required pilot pressure at a
1:1 ratio
Features
Hardened spool and cage for long life.
