Description
The PD42-S50X is a screw-in, cartridge style, pilot-operated, spool type hydraulic directional valve.
Operation
In neutral position the valve allows flow from port 2 to port 3 bidirectionally, while port 4 is blocked. On remote pilot signal at port 1, the valve's spool shifts to allow flow from port 3 to port 4, while blocking flow to port 2. Since port 5 is common to the spring chamber, pressure on port 5 will directly (1:1) affect the pilot pressure required and must be added to the bias spring value. Flow rates for sealed spool options when shifted to connect different directions are diminished by added friction (refer to flow rating table).
