FLOW CALCULATIONS
The Minimum Flow is calculated from the minimum recommended pressure drop,
1 ft WG (=3.0 kPa)
The Nominal Flow is from the maximum setting of the valve and the minimum recommended pressure drop,
2 ft WG (=6.0 kPa)
The Maximum Flow is calculated from the maximum setting of the valve and the max pressure drop,
20 ft WG (=60.0 kPa)

Example: A 1” valve is
required to be open 8 turns for
a Cv value of 7.5 at a flow rate
of 10 gpm and a pressure drop of 4ft.
Installation Recommendations
Install the valve in the correct flow direction
according to the arrow on the valve body and the
distance parameters detailed in Figure 1.
(Note: D = pipe diameter).
For Series STVL, cover the valve body with a wet
cloth when soldering to prevent premature deteriora-
tion of valve components.
When used with a pump, it is recommended to use a
straight length of pipe totaling 10 x D (instead of 5 x
D) upstream or downstream to avoid turbulence that
will affect the measuring accuracy. See Figure 2.
Turbulence can influence the measurements by up to
20% if this recommendation is not followed.
Flow Measurement & Accuracy
The measuring instrument connects to the test ports of
the valve and is pre-programmed with Macon Balanc-
ing characteristics. The pressure drop and flow read-
ings can be read off the display. If access to a Macon
Balancing instrument is unavailable, other industry
models are compatible. In addition, the flow can be
determined using the pressure drop diagram that is
included in the operating instructions with each
Macon Balancing valve.
The accuracy is highest when the valve is fully open.
Therefore, it is recommended to choose a valve that
can be opened at least three turns at the calculated
pre-setting value. Figure 3 represents the flow
measurement deviation in relation to handwheel turns.
Correction for Liquids
Applies to liquids other than water. Correct the meas-
ured flow (q) by the density (Y) according to this
formula. See Figure 4.
Sizing a Balancing Valve
When the differential pressure and design flow are
known, use this formula to calculate Cv value.
See Figure 5.
Memory Stop
1. Set valves to desired position.
2. Turn the inner stem with a 3 mm Allen wrench
in a clockwise direction until it stops.

sponding valve setting posi-
tion.
For the highest level of accu-
racy, it is recommended to
choose a valve that has at
least 3 open turns.
Example: A 1” valve is
required to be open 8 turns for
a Cv value of 7.5 at a flow rate
of 10 gpm and a pressure drop of 4ft.
Installation Recommendations
Install the valve in the correct flow direction
according to the arrow on the valve body and the
distance parameters detailed in Figure 1.
(Note: D = pipe diameter).
For Series LL-STVL, cover the valve body with a wet
cloth when soldering to prevent premature deteriora-
tion of valve components.
When used with a pump, it is recommended to use a
straight length of pipe totaling 10 x D (instead of 5 x
D) upstream or downstream to avoid turbulence that
will affect the measuring accuracy. See Figure 2.
Turbulence can influence the measurements by up to
20% if this recommendation is not followed.
Flow Measurement & Accuracy
The measuring instrument connects to the test ports of
the valve and is pre-programmed with Macon Balanc-
ing characteristics. The pressure drop and flow read-
ings can be read off the display. If access to a Macon
Balancing instrument is unavailable, other industry
models are compatible. In addition, the flow can be
determined using the pressure drop diagram that is
included in the operating instructions with each
Macon Balancing valve.
The accuracy is highest when the valve is fully open.
Therefore, it is recommended to choose a valve that
can be opened at least three turns at the calculated
pre-setting value. Figure 3 represents the flow
measurement deviation in relation to handwheel turns.
Correction for Liquids
Applies to liquids other than water. Correct the meas-
ured flow (q) by the density (Y) according to this
formula. See Figure 4.
Sizing a Balancing Valve
When the differential pressure and design flow are
known, use this formula to calculate Cv value.
See Figure 5.
Memory Stop

FLOW CALCULATIONS
The Minimum Flow is calculated from the minimum recommended pressure drop,
1 ft WG (=3.0 kPa)
The Nominal Flow is calculated from the maximum setting of the valve and the minimum recommended pressure drop,
2 ft WG (=6.0 kPa)
The Maximum Flow is calculated from the maximum setting of the valve and the maximum pressure drop,
20 ft WG (=60.0 kPa)

valve size and corresponding
handwheel setting to fulfill
the application requirements.
Determine the required flow
in the circuit (A) and the

Example: A 4” valve is
required to be open 7.5 turns
for a Cv value of 160 at a

Installation Recommendations for
GROOVED END VALVE CONNECTIONS
Grease the pipe ends, valve ends and rubber gasket lip
with grease, graphite paste or similar grease. Slip the
rubber gasket over the pipe end of each joint. Slide the
gasket past the grooves. Position the grooved end valve
between the pipe ends and slide the gaskets back into the
central spanned position.
All products have a flow direction arrow. Make sure that
it is pointing in the direction of the flow. Apply grease
on the outside of the gasket. Install housing clamps over
the gasket - insert bolts and nuts.
Tighten nuts evenly, using socket or other wrench. Tight-
en so that housing clamps come together evenly. The
connection is complete when housing clamps meet metal
to metal. Further tightening of bolts is not necessary.
Pre-assemble large diameter multi-segment housing
clamps loosely and install them as half-housings. Take
up evenly from top to bottom on alternate bolts.
Correction for Liquids
Applies to liquids other than water. Correct the measured
flow (q) by the density (γ) according to this formula.
