Installation Instructions:
The 2300 Direct Operated Reducing Valve is designed for dead-
end water service where the flow is intermittent and changes
rapidly, as on domestic water systems. It is especially effective
in regulating the flow of water to such fast acting equipment as
flushometers and snap cocks. The design is self contained, no
control pipe is required.
The preferred position for the 2300 is in a horizontal line with the
spring chamber up. When so mounted, the tendency of sedi-
ment to settle in the control ports is practically eliminated.
