PCV0.S10 VALVE SERIES
SAE Cartridge - 350 bar
Pressure compensator
Priority on demand
DESCRIPTION
The PCV is a screw-in, cartridge style, priority- on-demand, pressure compensator with a static load sense. The valve delivers
required priority flow (0 to max. available) on demand to 4 regardless of load pressure; inlet flow is at 3. In idle position, the valve will
deliver all input flow at 3 to the priority port 4. Increasing pressure at 4 (applied to the spool against the spring force) will result in an
increasing excess flow exit at 2 (by-pass of input flow). Excess flow at 2 can be used for auxiliary functions. Port 1 is the load sense
pressure port. Pressure at 1 assists the spring and moves the spool back so priority flow is supplied.
