V46 Series Pressure-Actuated Water-Regulating Valves
The V46 pressure-actuated modulating valves come in
two types of control action: direct acting or reverse
acting. Direct-acting V46 valves are typically used for
regulating refrigerant head pressure in water-cooled
condensers. Reverse-acting V46N valves are typically
used for bypass service on refrigeration systems and
heat pump applications. Commercial V46 valves may
be used with standard non-corrosive refrigerants.
V46 models are also available for ammonia refrigerant.
For applications where the coolant may be corrosive to
the valve trim, maritime models are available, which
have nickel copper (monel) valve trim.

pplication Overview
A
The V46 direct-acting models open on an increase in
pressure. Models A, B, and C are typically used for
regulating water-cooled condensers, while the low flow
“D” model is generally used in ice machines. The
reverse-acting V46N valve model closes on an
increase in pressure and is typically used for bypass
service on refrigeration systems and heat pumps that
control water temperature.
Commercial V46 valves are available in 3/8 in. through
2-1/2 in. sizes. Commercial all range models
(3/8 through 1-1/2 in.), may be used with standard
non-corrosive refrigerants, or ammonia refrigerant
applications, depending on the model.
V46 series valves also come in models designed for
Navy or maritime salt water applications. These valve
bodies are constructed of bronze, and any metal parts
that come into contact with salt water are constructed
of nickel copper (monel), which withstands the
corrosive action of salt water.
IMPORTANT: All V46 Series water regulating
valves are designed for use only
as operating devices. Where
system closure, improper flow, or
loss of pressure due to valve
failure can result in personal
injury and/or loss of property, a
separate pressure relief or safety
shutoff valve, as applicable, must
be added by the user.

Follow Steps 1 through 3, and use the information
obtained to locate a point on one of the flowcharts
found under
steps.
1. Determine maximum water flow required using
tables provided by the manufacturer of the
condensing unit, or calculate the flow using the
following formula:
Flow(GPM)

=
500x(Outlet -Inlet Temperature)
that satisfies all three
Note: If the outlet water temperature is unknown,
assume it to be 10°F below the
condensing temperature.
Example: A 9 ton capacity system has an inlet
water temperature of 65°F and an
outlet water temperature of 95°F.
The maximum required water flow is:

the valve opening point.
a. Valve closing point (to assure closure under all
conditions) must be the refrigerant pressure
equivalent to the highest ambient air
temperature the equipment will be subjected to
in the off cycle. Read this in psig from a
“Saturated Vapor Table” for the refrigerant
selected.

Page 3
b. To determine the valve opening point, add
about 7 psig (48 kPa) to the closing point.
c. From the same table, read the operating head
pressure corresponding to the selected
condensing temperature.
d. Subtract the valve opening point from the
operating head pressure. This gives the head
pressure rise.
3. Determine water pressure drop across the valve.
This is the pressure actually available to force
water through the valve.
a. Determine minimum water pressure available
from city mains or other sources.
b. From condensing unit manufacturer’s tables,
read the pressure drop through condenser
corresponding to the required flow.
c. To the value found in 3b, add the estimated or
calculated drop through installed piping.
d. Subtract the total condenser, piping, and static
head (if applicable) pressure drop from the
available water pressure found in 3a. This is
the available pressure drop across the valve.
4. Select the proper valve size from the V46
flowcharts by locating a point on a chart that will
satisfy the flow, the head pressure rise above
opening point, and the pressure drop across the
valve.
Example: The required flow for a low-range system is
found to be 27 GPM. Condensing pressure
is 125 psig, and the maximum ambient
temperature is estimated at 86°F. City water
pressure is 40 psig and the manufacturer’s
table gives a pressure drop through the
condenser and the accompanying piping
and valves at 15 psi. Drop through the
installed piping is approximately 4 psi.
Step 1: 27 GPM
Step 2: Closing point is pressure of refrigerant
corresponding to 86°F = 93 psig
Opening point = 93+7 = 100 psig
Operating head pressure = 125 psig
Head pressure rise = 125-100 = 25 psi
Step 3: Minimum pressure = 40 psig
Pressure drop through condenser = 15 psi
Combined pressure drop = 15+4 = 19 psi
Pressure drop across valve = 40-19 = 21 psi
Using a flow of 27 GPM, a head pressure rise of
25 psi, and a pressure drop across the valve of 21 psi,
the only valve that satisfies all three criteria is a
1-1/4 in. valve. See the 1-1/4 in. V46 - All Range chart
on the next page.

Note: The maximum differential water pressure
across a valve is 60 psi.

CAUTION: Equipment Damage Hazard.
To prevent damage to the
capillary, avoid sharp bends or
kinks in the capillary. Coil and
secure excess capillary at the
valve end to avoid tube breakage
due to vibration. Because
harmonic vibration can also break
the tube, some slack must be left
in the capillary. Do not permit the
tubing to rub against metal
surfaces where friction can
damage the capillary.
Flush water lines to clear any foreign matter that may
interfere with valve operation. Mount valves vertically
on the inlet side of the condenser with spring housing
up. If it is necessary to keep the condenser flooded
with coolant, the valve can be mounted on the outlet
side. When mounting the valve in a position other than
vertical, follow the instructions of the equipment in
which the valve will be installed. Make refrigerant head
pressure connection to bellows. If additional capillary
tubing is required, use 1/4 in. O.D. tubing or larger.
djustment
A
Valves may be adjusted with standard service valve
wrenches or screwdrivers, see Table 5. All range
valve settings can be changed quickly from low-range
refrigerants such as R134 to high-range refrigerants
such as R22 or vice versa. To raise the valve opening
point, turn the adjusting screw, located at the top of
range spring housing, counterclockwise. See Figure 8.
Turn the adjusting screw clockwise to lower the
opening point. Exact settings can be made using a
pressure gauge in the refrigerant line to determine the
throttling point. Put the system under normal operating
load and adjust to the desired operating pressure. See
Table 14 for pressure range specifications.

If the compressor operates in high ambient
temperatures, head pressures may remain high
enough during off cycles to prevent the valve from
closing completely. In such instances, the opening
point of the valve should be raised just enough to
cause the valve to close during compressor standby
periods. This will also raise the throttling point.

To clear any sediment that might accumulate, valves
may be manually flushed. Insert screwdrivers under
