PRESSURE COMPENSATOR
135 136
PCV1.S08 VALVE SERIES
SAE Cartridge - 350 bar
Pressure compensator
Flow on demand
DESCRIPTION
A screw-in, cartridge style, direct acting, spool type pressure compensator valve. Main use is into load-indipendent
applications. The PCV1 allows flow from port 2 (usually pump) to 3 (usually load), while port 1 senses load pressure rise.
When the pressure drop between port 3 and 1 varies, the valve re-calibrates its pressure rise to get a constant pressure rise
and flow regulation.
