DESCRIPTION
Bell & Gossett Circuit Sentry
Commissioning Valves are precision engineered valves
used in heating and cooling systems for the distribution
of flow in various sections of the system. The dynamic
balancing and commissioning valve ensures easy and
reliable balancing of the system, regardless of any
fluctuations in the differential pressure of the system.
The Bell & Gossett Circuit Sentry Flo-Setter limits the
maximum flow in the system and can be used in both
variable and constant flow systems. The clear scale on the
lockable handle ensures that flow setting is simple and
user friendly while the integral P/T ports allow verification
of pressure.
INSTALLATION INSTRUCTIONS
Circuit Sentry Flo-Setter Balance & Commissioning
Valves are uni-directional valves and can be installed in
most altitudes; however, they should be installed in a
position to facilitate the ease of balancing the system. Be
sure to install the Circuit Sentry Flo-Setter with the arrow
pointing in the direction of flow.
CIRCUIT BALANCE VALVES
WITH NPT CONNECTIONS
Apply pipe compound conservatively to male
connecting fittings only.

OPERATION INSTRUCTIONS
HOW TO USE BELL & GOSSETT CIRCUIT SENTRY
FLO-SETTER BALANCE & COMMISSIONING VALVES
FOR PRE-SET FLOW BALANCING
The Circuit Sentry Flo-Setter Balance & Commissioning
Valve is easily set, and the pre-setting is read on the
scale. The flow rate of the valve can be determined from
the flow rate graphs for the valve dimension in question.
See the flow rate graphs of the valve in the FLOW CURVE
BOOK (G10092) or Submittal (A-609.22 or A-611) for
further information about the adjustment setting.
Select the appropriate size Circuit Sentry Flo-Setter
Balance & Commissioning Valve (normally line size) for
the required GPM.
Please note: The scale is for the adjustment of flow. If you
want to close the branch line, use an isolation ball valve
in conjunction with the Circuit Sentry Flo-Setter.
The handle can be locked after adjustment. Remove the
B&G logo cap and tighten with 5mm hexagonal key.
HOW TO USE BELL & GOSSETT CIRCUIT SENTRY FLO-
SETTER TO PROPORTIONAL BALANCE A SYSTEM
The system is easily balanced by adjusting the pump
according to the required differential pressure across the
critical valve.
When the differential pressure is available the system will
automatically be balanced.
