1 Description
The D-DS06 valve can be used for systems with constant
and variable pumps. The internal load signal avoids unnec
essary energy losses. The pressure losses in neutral circu
lation are constant regardless of the number of valves, in the
partial load range the excess oil quantity flows to the tank
only against the working pressure. The valve is designed for
harsh operating conditions in agricultural and construction
application. Due to the Zi-Ni coating and the high switching
force, the D-DS06 is perfectly suited for these applications
and designed for a long service life.
