RPGT-LWN-CAW
SOFT START RELIEF VALVE
FEATURES
 Valve provides protection for pumps and motors
from pressure transients due to sudden load
changes
 Valve provides protection for hydrostatic drives by
reducing the jerk caused by sudden reversals.
The valve is suitable for cross-port applications
 Small pumps can be started against a soft relief
to provide longer pump life
APPLICATIONS




Blower hydraulic drives
Vacuum tanker hydraulic drives
Compression hydraulic drive
Other shock load prone systems
SCHEMATIC
USE AND OPERATION
The RPGT is a two-stage, pilot operated, seated relief
valve that limits maximum system pressure and also
limits the rate of pressure rise. The valve ramps open at
a constant speed, independent of settings and flows
and takes approximately 250 ms to shift from minimum
to maximum setting. The adjust screw determines the
maximum (relief) setting and the minimum (threshold)
setting.
