Modularity and efficiency
For the most demanding applications, only the highest flow and the highest pressure will do.
The PVG 128/256 are built to take control with up to 500 l/min per section supplied with up to 1200 l/min (300 US gal/min) pump flow.
Rock-solid control and optimum safety are more critical than ever when it comes to the biggest applications and the heaviest tasks.
This new proportional (pre-compensated) load-sensing valve series can easily be built together with PVG 32 and PVG 16 making it easy to build a valve that is adapted to the flow needs of the most demanding application.
Application opportunities
Go with our PVG 128/256 and optimize work functions on cranes, mining, drill rigs and marine applications like winches and bow thruster.
