Bell & Gossett V58045B Circuit Setter Plus MC - Manual

DESCRIPTION
Circuit Setter Balance Valves are precision engineered valves
which function as precise system balance valves and highly
accurate variable orifice flow meters. Circuit Setter Balance
Valves are equipped with an easy to operate memory stop
feature. NPT and Sweat models are also equipped with a
drain port feature.
INSTALLATION INSTRUCTIONS
NPT and sweat style Circuit Setter Balance Valves are
equipped with a 1/4" NPT plugged drain port. If the drain port
is to be used to drain a riser on the downstream side of a ter-
minal unit, it should be situated on the terminal unit side of
the riser when installing the Circuit Setter.
FOR INSTALLING SWEAT CONNECTION:
a) Clean tube ends and valve connections thoroughly per
good piping practices with a fine grade emery cloth or fine
grit sandpaper.
b) For soldering, use 95-5 (Tin-Antimony) solder and a good
grade of flux.
c) Use a torch with a sharp pointed flame.
d) When sweating the joints, first adjusting the valve in the full
open position, then wrap the valve with a cool wet rag and
then direct the flame with care to avoid subjecting the valve
to excessive heat. Allow the valve to cool before touching
or operating.
