Danfoss Valve PVG 128, 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.
Features of the PVG 128 valve :
- Inlet flow up to 1200L/min { 317 US gal/min }
- Compact sectional platform solution for easy integration with PVG 16 and PVG 32
- Load independent flow control :
- oil flow to an individual function is independent of the load pressure of this fuction.
- oil flow to one function is independent of the load pressure of other functions.
- Reliable regulation characteristic across the entire flow range.
- Load sense relief valves for A and B enables reduced energy loss at target pressure.
- Optimized for lower pressure drop and higher efficiency.
- Several options for connection threads and flange mount.s
- Compact design, easy installation and serviceability.
- Static load sense system when selecting pump control.
- Internal To connection in all PVSI/PVGI.

The compensated PVB is intended for controlling a work function where the function behavior in terms of flow and pressure requires independency on the load pressure of other function used simultaneously.
The compensator is a 3-way type which include load drop check valve functionality, compensator and neutral relief which A and B port pressure build up in neutral.
