HIGH/LOW PRESSURE
CUT-OUT VALVES
Type VEP
Operation
Recommended for systems powered by two pumps where double speed (fast-slow
sequence) is made available. Fast speed is obtained by summing up both pumps
capacity up to the setting value of the VDS valve. Slow speed according to the
small pump is obtained by later discharge of the bigger pump. Working pressure
during slow speed is controlled bu the VMP valve.
