LS Compensating Valve
PVFC
This Tech Note introduces LS compensating valve PVFC. PVFC is an important step towards the elimination of typical regulation problems that arise when, for example, PVG is used with LS-pumps that
yy lead an oil flow into the LS-line
yy are fitted with a high leakage LS-control
In the first case PVFC is used as an LS-controlled pressure relief valve. In the second case it is used as an LS-controlled pressure regulator.
PVFC must only be sold together with other hydraulic components from Danfoss.
