Nelson 800 End gun valve with Stud Kit

The 800P Brings the 800 series control valve to the SR75 and SR100 End Guns operating with a booster pump. When the booster pump is turned on, the added pressure causes the valve to open thus eliminating the need for a solenoid (skinner valve) that is known to have plugging issues and failure.  The 800P can also be operated with a solenoid when a booster pump is not present.  Included is a ball drain/vent to be installed either in the booster pump volute or the valve jacket to ensure proper pump priming.
