The PE12-S67H is a screw-in, cartridge-style, proportional, spring centered spool, pilot operated hydraulic directional valve.
In neutral position inlet port 3 is blocked and ports 2, 4 and 5 are communicating with each other. On remote pilot signal at port 1 the valve's spool shifts proportionally to the applied pilot pressure to allow flow from port 3 to port 4, thru a load, such as hydraulic cylinder or motor, and then from port 2 to port 5 and to tank. On remote pilot signal at port 6 the valve's spool shifts proportionally to the applied pressure in the opposite direction, thus reversing the flow direction. The valve's spool is symmetrical providing meter-in and meter-out control.
NOTE: Orifice diameter between ports 2 and 4 and port 5 in neutral position: 0.79 mm (0.031 in).
- Hardened spool and cage for long life.
- Excellent metering characteristics.
- Good Linearity.
