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 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 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 ow

rates over the pressure range. See Table 4 for color codings, and injector graphs for total, slow rinse and draw 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 downow (for softeners or regenerating 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 rell elbow.

Rell Flow Control Assembly or Rell Port Plug

The rell ow control assembly consists of a rell ow elbow, rell ow control retainer assembly, rell ow control, polytube

insert and nut assembly. The rell ow control retainer ts in the rell elbow. The rell ow control retainer houses the rell ow

control which controls the ow rate when the regenerant tank is being relled. The rell ow control is a exible washer-like

part with a small orice and a precision molded contour that delivers a steady 0.5 gpm regenerant tank rell rate at varying inlet

pressures. Rell is accomplished with treated water.

Actual tank size used may vary depending on the design and application of the system. Tank diameter is an approximation for a

downow softener using standard mesh synthetic cation exchange media regenerating with sodium chloride.
