V43/V243 Series Pressure-Actuated Water-
Regulating Valves Product/Technical Bulletin
Introduction
The V43/V243 Pressure-Actuated Water-Regulating Valves
regulate water flow through the condenser of large
refrigerated cooling systems. These pilot-operated valves
open on an increase in refrigerant head pressure and
facilitate modulating operation.
The V43/V243 water-regulating valves are available for
commercial and maritime applications.
V43 valves are available for noncorrosive low- and
medium-pressure refrigerants such as R-134A, R-404A,
R-502, and R-507.
V243 valves are available for noncorrosive high-pressure
refrigerants such as R410A.
Commercial V43/V243 valves feature a cast-iron body,
brass internal parts, and bronze seat material.
To resist the corrosive action of sea water, the V43/V243
maritime and Navy models feature a red brass body,
bronze and MONEL® interior parts, and MONEL seat
material.

Application
Important: All V43/V243 water-regulating valves are
designed for use only as operating devices. Where
valve failure can result in personal injury and loss
of property, it is the responsibility of the installer to
add and maintain devices (pressure relief or safety
shutoff) or systems (alarm or supervisory) that
protect against, or warn of, device failure.
Note: The V43 and V243 Series Head Pressure
Regulating Valves are available for cooling
applications only (direct acting).
Operation
The V43/243 valves are refrigerant-actuated units that
require only system refrigerant head pressure to operate.
The valve does not require electrical power: if you make
the inlet and outlet water lines and refrigerant head
pressure connections, the valve functions.
Refrigerant head pressure drives a built-in pilot valve that
operates the main valve. Water and spring pressures are
the main valve's opening and closing forces.
The main valve seat disc assembly is suspended on a
heavy-duty rubber diaphragm, eliminating any close-
fitting or sliding parts. This reduces friction within the
valve, facilitating more reliable control. This also reduces
the chance of the valve stem sticking in dirty water
conditions.

Determining the required valve size
Every system is unique and requires specific engineering
data to correctly size and design. Typically, a valve is
replaced with another valve of the same size.
Important: An undersized valve does not deliver
the required amount of water flow under full load
conditions, and an oversized valve tends to hammer
under low load conditions.
To select the correct valve size, determine the following
variables:
• Maximum water flow required
• Available water pressure drop across the valve, also
known as the differential
Use these variables to locate a point on one of the flow
capacity charts (from Figure 6 to Figure 13) that slightly
exceeds the maximum water flow that you need. The
flow capacity chart that contains this point represents the
correct valve size.
Maximum water flow required
Use the information that the manufacturer of the
condensing unit provides to determine the maximum
water flow that you require. If this information is not
available, calculate the maximum water flow with the
following formula:
Example: If a 100-ton capacity system has an inlet water
temperature of 85°F and an outlet water temperature of
95°F, the maximum water flow that you require is:
Available water pressure drop across the
valve
The available differential, or water pressure drop, across
the valve is the supply pressure to the valve minus all
downstream pressures. This pressure drop is the force
available to push water through the valve.
Water supply pressure is the water supply pressure to the
inlet side of the valve from a cooling tower, a city water
main, or other source.
Figure 2: Pressure drop across the valve
Opening point and refrigerant head
pressure rise
The forces that operate the valve are refrigerant head
pressure, water pressure, and spring pressure. These
forces oppose each other.
When the head pressure rises, and the refrigerant
pressure overcomes the spring force of the pilot valve,
the valve begins to open; the disk lifts off of the seat. This
point is called the opening point.
You can adjust the opening point if you use the
adjustment stem to increase or decrease the spring force.
If the head pressure continues to rise, the refrigerant
pressure further opens the valve until the valve is fully
open. The range from the opening point when the valve
lifts off the seat to the point when the valve is fully open is
called the throttling range.
The throttling range is fixed and you cannot adjust it.
The throttling range is approximately 40 psig for the low-
pressure V43 Series valves, approximately 50 psi for the
medium-pressure V43 Series valves, and approximately 60
psi for the high-pressure V243 Series valves.
Head pressure rise above the opening
point
When the head pressure rises, the force of the refrigerant
head pressure overcomes the spring force and any
hysteresis, and pushes the disc off the seat, facilitating
water to start to flow through the valve.
Anything above that point is head pressure rise above the
opening point. In standard scenarios, the opening point is
approximately 7 psi above the closing point.

Choosing the correct valve size
About this task:
A correctly sized valve meets the requirements of the
maximum water flow that you need but functions at
an acceptable level when you need minimum flow. It
does not water-hammer, cut, or wire-draw the seats and
seating discs. To select the correct valve size for your
application, see V43 capacity flow charts and V243 capacity
flow charts.
Use the following steps to determine the appropriate
valve size for your application:
1. Locate the point where the valve is fully open on
the y-axis. See Figure 3.
2. Draw a horizontal line from this point to where the
line intersects with the water pressure available
(WPA) curve. This is Point A.
3. Draw a vertical line from point A to where it
intersects with the x-axis. This is Point B.
Point B is the maximum amount of water that the
valve can flow, when fully open, under the stated
conditions. See Figure 3.
4. Locate the maximum water flow that you need for
your application on the x-axis. This is Point C.
5. Draw a vertical line from Point C to where the line
intersects with the WPA curve. This Point D.
6. Draw a horizontal line from Point D to the left
where it intersects with the refrigerant head
pressure rise above opening point.
This is where the selected value meets the maxi-
mum flow requirement of the application.
Figure 3: Capacity chart
Use the flow charts to select the valve that is most
appropriate for your application.
Example
In this example, the required flow for an R-404A system
is 300 gpm. The cooling tower pump discharge pressure
is 30 psig, and the condenser manufacturer's table gives
a pressure drop of 8 psid through the condenser. The
pressure drop through the installed piping, fittings, and
valves is approximately 12 psi.
Maximum Water Flow Required = 300 gpm
Water Pressure Available= 30 - (12 + 8)
Water Pressure Available= 10 psid
You need to select the proper valve size. The proper size
valve is indicated by the flow chart that slightly exceeds
the maximum required flow when the valve is wide open.
As indicated in Figure 5, the correct valve for this
application is a 3-in. medium-pressure (160/260 psi),
noncorrosive, commercially constructed V43 Series Valve.
The maximum water flow that a 3-in. valve can deliver
(330 gpm) under the stated condition is slightly greater
than the maximum water flow required (300 gpm).
Figure 4: Example values
Note: The maximum flow required for the
application is to the left of the dotted vertical line
between Point A and Point B (300 gpm when the
valve is approximately 72% open).
Figure 5: Correct valve size for the application
Select the valve type from Table 4 through Table 6.

Installation and initial adjustment
1. Flush the lines to remove any foreign matter before
you connect the lines to the valve. See Servicing.
2. Screw each companion flange and gasket onto
the inlet and outlet water lines. See Figure 14. The
inside of the companion flange is threaded. For
flange and gasket kit information, see Table 9.
3. Mount the V43/V243 valves so that the water flow
follows in the direction indicated by the arrow on
the V43/V243 casting.
Note: Mount the V43/V243 valves onto a
horizontal water line, with the bellows up.
4. Secure the inlet and outlet water lines with
companion flange and gasket to the inlet and
outlet flange connections on the V43/V243 valves
with hex bolts and nuts.
Figure 14: V43/V243 gasket and flange connections for
V43AV
5. Connect a 1/4-inch copper (or UltraCap) tube
from the bellows of the V43/V243 valves to the
refrigerant line. See Figure 15. In reciprocating
compressor applications, make the refrigerant
connection as far from the compressor discharge
as possible. If possible, make the connection on the
outlet side of the condenser.
6. Manually flush the valve to remove debris. See
Servicing.
7. Put the system into operation under normal
operating conditions.
8. Determine the correct refrigerant operating head
pressure for the system. Observe the refrigerant
pressure that the high side pressure service gauge
indicates.
9. If necessary, adjust the operating head pressure.
See Adjusting the valve.

V43AV
Checkout procedure
Note: Before you operate equipment, always
manually flush the valve. See Servicing.
Before you leave the installation site, observe at least
three complete operating cycles (bellows open and close)
to verify that all components function properly.
Adjusting the valve
About this task:
Make adjustments gradually. Adjust by a 1/2 revolution
at a time. Wait for the system to stabilize after each
adjustment change. The throttling range, also known as
the differential, is not adjustable.
• To increase the opening point of the valve, turn the
adjusting screw inward, clockwise, away from main
valve body as viewed from the bottom up. See Figure
16.
• To decrease the opening point, turn the adjusting
screw outward, counterclockwise, toward the main
valve body.
V43/V243 Series Pressure-Actuated Water-Regulating Valves Product/Technical Bulletin6

Servicing
You can disassemble, clean, and reassemble the V43/V243
valves without breaking the line connections.
Accessing internal parts
1. Shut off the water flow to the V43/V243 valves.
2. Remove the hex bolts from the top of the bellows
flange. See Figure 16.
3. Remove the bellows flange.
Note: For internal parts replacement
instructions, refer to the respective
replacement parts instruction sheet.
Manually flushing the valve
About this task:
Before you start equipment, manually flush the valve to
remove any foreign material from the valve.
1. Turn the adjusting screw clockwise, to raise the
adjusting screw away from the valve body as much
as possible. See Figure 16. Count the number of
turns for reference.
2. Insert a standard slotted screwdriver tip between
the adjusting screw and the push pin.
3. Pry the push pin down with the screwdriver to open
the valve as indicated.
4. Hold the push pin down to hold the valve open.
Flush the valve for several minutes, to remove all
foreign matter from the V43/V243 valves.
5. After you flush the V43/V243 valves, remove the
screwdriver and set the adjusting screw to the
desired operating pressure. See Adjusting the
valve.
Cleaning the MONEL screen
A fine mesh MONEL screen protects the pilot valve from
debris. To clean the screen, shut off the water supply,
relieve the water pressure, and unscrew the hex bolt. See
Figure 16. Remove the MONEL screen, brush, and rinse
clean.
Draining the V43/V243 valves during
shutdown
To reduce the possibility of freeze-up, drain the V43/V243
valves during shutdown. To drain, unscrew the drain plug
at the base of the V43/V243 valves. See Figure 16.
Note: In order to drain, you must mount the V43/
V243 valves in a horizontal water line with the
bellows up and the drain plug down.
