Injector Cap, Screen, Injector Plug and Injector
The screen, injector and/or injector plug(s) are installed under the injector cap in an easy to access location on top of the valve. The
injector cap contains four slots so no water accumulates in the cap. The injector cap is designed to be hand tightened.
Under the injector cap there is an easy to clean removable screen to prevent fouling of the injector. There are two holes under the
injector cap labeled “DN” and “UP”. The holes will be fi lled with a plug or an injector.
The plug (Order # V3010-1Z) prevents water from traveling a certain pathway. The injector lets water pass through the pathway.
The self-priming injector increases the velocity of the water, creating a zone of negative pressure that draws in the concentrated
liquid regenerant, such as sodium chloride (brine), potassium permanganate, etc. The regenerant blends with the stream of water,
which passes through the media to regenerate the bed.
The injector provides a consistent regenerant/water mixture ratio over the entire operating pressure range of the control valve. The
injector provides good performance in a variety of applications, which may involve elevated drain lines and long regenerant draw
lengths. Injectors are chosen by knowing the type, amount, and regenerant fl ow rate for a particular type of media. Guidelines can
be found in the media manufacturer’s literature. The color coded injectors give different regenerant draw, slow rinse and total fl ow
rates over the pressure range. See Table 4 for color codings, and injector graphs for total, slow rinse and draw fl ow rates.
The control valve has been designed so that the OEM can rapidly change the control valve to allow for the following options:
•
regeneration downfl ow (for softeners or regenerating fi lters install injector in DN location, plug in UP location); or
•
no regeneration (both the DN and UP holes have injector plugs installed) and plug installed for the refi ll elbow.
Refi ll Flow Control Assembly or Refi ll Port Plug
The refi ll fl ow control assembly consists of a refi ll fl ow elbow, refi ll fl ow control retainer assembly, refi ll fl ow control, polytube
insert and nut assembly. The refi ll fl ow control retainer fi ts in the refi ll elbow. The refi ll fl ow control retainer houses the refi ll fl ow
control which controls the fl ow rate when the regenerant tank is being refi lled. The refi ll fl ow control is a fl exible washer-like
part with a small orifi ce and a precision molded contour that delivers a steady 0.5 gpm regenerant tank refi ll rate at varying inlet
pressures. Refi ll is accomplished with treated water.
2 Actual tank size used may vary depending on the design and application of the system. Tank diameter is an approximation for a
downfl ow softener using standard mesh synthetic cation exchange media regenerating with sodium chloride.
