Product Overview

Flow rate adjustment, threaded version
The flow rate is adjusted as follows:
A. With the aid of the flow rate
indicator (1), mark the desired
flow rate.
C. While holding the bypass valve open, use a wrench to turn the valve
control stem (4) to adjust the flow rate slowly. The resulting flow rate is
indicated by the metal ball (5) that slides up and down inside a transpar-
ent channel (6) marked by a graduated scale in GPM.
D. Once the flow rate is properly adjusted, release the operating ring
(2) of the bypass valve. The valve will automatically return to the closed
position by means of an internal spring.
E. A replacement bypass valve stem (7) with operating ring is available in
event it is damaged and inoperable. Order code F19346.
B. Use the operating ring
(2) to open the bypass valve
slowly. This allows fluid to flow
through the flow meter (3). The
bypass valve is automatically
closed under normal operating
conditions.
