The refill flow control assembly is installed in an easy to access refill elbow located on top of the control valve. The refill flow
control assembly is attached to the control valve with a locking clip. The locking clip allows the elbow to rotate 270 degrees so the
outlet can be orientated towards the regenerant tank.
The control valve has a standard refill elbow to which a 3/8” flexible tube can be connected. An optional elbow can be ordered
which accommodates a ½” flexible tube for a high regenerant draw rate situation (G injectors and larger). Both elbows use the same
refill flow control and retainer.
If the control valve is to be used as a non-regenerant filter control valve, the refill elbow is removed and replaced with a refill port
plug P/N V3195-01.
Drain Line Flow Control and Fitting Assembly
The drain line flow control assembly includes a drain line flow control and a fitting. The drain line flow control allows proper media
bed expansion by regulating the flow rate to the drain. The drain line flow control is a flexible washer-like part with an orifice and
a precision molded contour. The flow rates are within
±
10% over the pressure range of 20 psi to 125 psi. See Table 5 for flow rate
information.
The drain line flow control and fitting are located on top of the control valve and replaceable without the use of special tools.
The drain line flow control can be installed in the standard ¾” drain line elbow, which accommodates 5/8” polytube or ¾” NPT drain
line connections. The optional nut and polytube insert for the ¾” drain line elbow is designed for use with flexible polytube only.
The ¾” drain line elbow can be rotated 180 degrees so the outlet can be orientated to the nearest drain. The same retainer is used for
all drain line flow controls for the ¾” fitting. Drain line flow controls designed for the ¾” fitting are available for flow rates ranging
from 0.7 to 10 gpm.
An optional 1” straight drain line fitting is available to accommodate drain line flow rates ranging from 9 to 25 gpm. This fitting is
straight but still connects to the control valve using the same locking clip. The drain line flow control is located between two fitted
parts (i.e. the fitting acts as the retainer). The nut is unscrewed to access the drain line flow control.
