Description
The PD16-42 is a screw-in, cartridge style, pilot operated, spool-type hydraulic directional valve.
Operation
In the neutral position the valve allows flow from port 3 to 2, while port 4 is blocked. On remote pilot signal at port 1 the valve shifts to open from 3 to 4, while blocking flow to port 2. Since port 4 is common to the spring chamber, pressure on port 4 will directly (1:1) affect the pilot pressure required and must be added to the bias spring value.
Features
- Hardened spool and cage for long life.
- Optional sealed pilot
- Industry-common cavity.
