Will a Symcom or Pumtec work with a Dole Valve or CSV?

  When restricting the pump flow with a valve, will the pump produce a higher load that is less likely to cause a "run dry" condition for a Symcom or Pumptec?

Actually, pumping through a flow control valve directly will reduce the load, not increase the load.  Devices like the Symcom or Pumptec are not adjustable enough to distinguish the difference in amperage between the low load of the pump being restricted, and the slightly lower load that happens when the pump runs dry.  You need a device that CAN distinguish the difference in load.  That is what a Cycle Sensor does.  It is designed to work with the decreased pump load when using a Cycle Stop Valve, so it will also work with the reduced load caused by a flow control valve.  See this link.
