Data Sheet
Proportional Valve Group
PVG 128 and PVG 256
PVG is a hydraulic, load-sensing proportional valve,
designed for optimal machine performance and
maximum design flexibility.
The PVG 128 and PVG 256 are new members of the
PVG product platform.
PVG 128 and PVG 256 controls work port flow up to
500 l/min and up to 420 bar work port pressure.
The PVG valve design is based on a modular concept
that enables machine designers to specify a valve
solution suitable for multiple market segments across
multiple applications.
The load independent proportional control valve and
high performance actuator technology combined
with a low pressure drop design improves the
machine performance and efficiency—Increasing
productivity and reducing energy consumption.
Features

Inlet flow up to 1200 l/min [317 US gal/
min]
•
Maximum work port flow 500 l/min
•
Compact sectional platform solution for
easy integration with PVG 16 and PVG
32
