- FEATURES
- PERFORMANCE
PV32 is a hydraulic load sensing valve designed to give maximum flexibility. From a simple load sensing directional valve, to an advanced electrically controlled load-independent proportional valve. PV32 modular system makes it possible to build up a valve group to meet requirements precisely. The compact external dimensions of the valve remain unchanged whatever combination is specified.
FEATURES
◼ Load-independent flow control:
- Oil flow to an individual function is independent of the load pressure of this function
- Oil flow to one function is independent of the load pressure of other functions
◼ Good regulation characteristics
◼ Energy-saving
◼ Up to 12 basic modules per valve group
◼ Several types of connection threads
◼ Low weight
◼ Compact design and installation
