Flow rate adjustment
The flow rate is adjusted as follows:
Complete closing and opening of the valve
The valve can be completely closed and opened. A slot on the
control stem indicates the valve position. When the control stem is
turned fully clockwise
(the slot is perpendicular
to the axis of the valve),
the valve is fully closed
(A). When the control
stem is turned fully
counter-clockwise (the
slot is parallel to the axis
of the valve), the valve
is fully open (B).
Insulation
The 132 series balancing valve
is supplied with a pre-formed
insulating shell. This system
ensures perfect thermal
insulation and keeps out water
vapor from the environment.
Additionally, this type of
insulation is ideal in cold water
circuits as it prevents
condensation from forming on
the surface of the valve body.

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 transparent 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.
AB
Completely closed Completely open
Installation
Install the balancing valve in a location that ensures free access to
the flow meter shutoff valve, control stem and flow rate indicator. To
ensure accurate flow measurement, straight sections of pipe
installed as shown is recommended.
The valve can be installed in any position with respect to the flow
direction shown on the valve body. Additionally, the valve can be
installed either horizontally or vertically.
Hydraulic characteristics at 100% open
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.
