The external handwheel control manually regulates the flow
from zero to maximum delivery by means of a threaded extension
that is used to position the angle of the reaction plate.
Changing this angle controls the length of the piston stroke,
thereby increasing or decreasing displacement of the pump.
Rotating the handwheel one turn results in approximately 1°
change in the angle of the reaction plate. One turn of the
handwheel changes the flow approximately 1.50 gpm at 1800
rpm (5.7 L/min at 1800 rpm) on the PV 310 series pump. One
turn of the handwheel changes the flow approximately 2.0 gpm
at 1800 rpm (7.6 L/min at 1800 rpm) on the PV 410 series pump.
A pressure relief valve must be incorporated
in the circuit to protect the system from excessive pressures.
