Bell & Gossett V58044B Circuit Sentry Automatic Flow-Limiting Valve - Manual

DESCRIPTION
The Bell & Gossett Automatic Flow Limiting Valves (AFLV) are
designed to automatically control the flow in piping system to
selected preset limit. As pressure differential increases, a
cartridge inside the valve body reduces the flow area to
accurately maintain the pre-selected flow rate.
Operational Limits
Maximum Operating Temperature: 250ºF (121ºC)*
Maximum Operating Pressure: 300 psig (2069 kPa)*
Differential Pressure Flow Control
2 to 60 psig (14 to 414 kPa) nominal
INSTALLATION INSTRUCTIONS
1. For installing NPT Connections:
a) Install the AFLV in the piping system/circuit where it is
desired to maintain the flow at a preselected value.
Apply pipe joint compound sparingly to the male pipe
threads only.
b) Install the unit so that the flow arrow on the body
housing points in the direction of flow.
c) Supports both sides of the unit with wrenches during
installation to prevent putting stress on the joint
joining the two sections.
2. For installing Sweat Connections:
a) Clean tube ends and valve connections thoroughly
according to good piping practices with a fine grade
emery cloth or fine grit sandpaper.

SAFETY
INSTRUCTION
This safety alert symbol will be used in this manual to draw
attention to safety related instructions. When used, the safety
alert symbol means ATTENTION! BECOME ALERT! YOUR
SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE IN-
STRUCTIONS MAY RESULT IN A SAFETY HAZARD.
CAUTION: The generous use of pipe joint com-
pound when installing the AFLV will foul the valve
operating mechanism preventing it from functioning
properly. Pipe joint compound must be conservatively
applied to male threads only. Failure to follow this
instruction can result in moderate personal injury and/or
property damage.
INSTALLER: PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.
* Refer to chart A for solder joints for limitations.
CAUTION: The use of PTFE impregnated pipe
compound and PTFE tape on pipe threads pro-
vides lubricity, which can lead to overtightening and
breakage. Do not overtighten. Failure to follow this
instruction can result in moderate personal injury and/or
property damage.
