[142] Circuit diagram: Flow division using restrictor
Throttle and orifice valves
control the volumetric flow rate in conjunction with a pressure
relief valve. The PRV opens when the resistance of the flow
control valve becomes greater than that of the opening pressure
set on the PRV. This produces a division of flow.
The volumetric flow to the load device varies, i.e. the action of flow control valves is load-dependent.
