V43/V243 Series Pressure-Actuated Water-Regulating Valves Product/
Technical Bulletin
The V43/V243 Pressure-Actuated Water-Regulating
Valves are designed to regulate water flow through the
condenser of large refrigerated cooling systems. These
pilot-operated valves open on an increase in refrigerant
head pressure and provide modulating operation.
The V43/V243 water-regulating valves are available for
commercial and maritime applications.
V43 valves are available for non-corrosive low- and
medium-pressure refrigerants such as R-134A,
R-404A, R-502, and R-507. Specially designed V43
valves are also available for ammonia service (R-717).
V243 valves are available for non-corrosive
high-pressure refrigerants such as R410A.
Commercial V43/V243 valves are constructed with 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 are constructed
with a red brass body, bronze and monel interior parts,
and monel seat material.
This product is made of a copper alloy, which
contains lead. The product is therefore not to be used
on drinking water.

Application
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,
requiring only system refrigerant head pressure to
operate (no electrical power is required). Only the inlet
and outlet water lines and refrigerant head pressure
connections need to be made for the valve to function.
A built-in pilot valve, driven by refrigerant head
pressure, operates the main valve using water and
spring pressures as the 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, allowing more reliable control. Also, the
chance of the valve stem sticking in dirty water
conditions is reduced.
Determining the Required Valve Size
Every system is unique and requires specific
engineering data to properly size and design. Typically,
a valve is replaced with another valve of the same size.
To select the correct valve size, determine the following
variables:
• Maximum Water Flow Required
• Available Water Pressure Drop (Differential) across
the Valve
Use these variables to locate a point on one of the flow
capacity charts (Figure 5 through Figure 12) that
slightly exceeds the maximum water flow required. The
flow capacity chart containing this point represents the
proper valve size.
Maximum Water Flow Required
Use the information provided by the manufacturer of
the condensing unit to determine the maximum water
flow required. If this information is not available,
calculate the maximum water flow required by using
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 required
is:
Available Water Pressure Drop (Differential)
across the Valve
The available water pressure drop (differential) 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 pressure supplied
to the inlet side of the valve from a cooling tower, a city
water main, or other source.
Opening Point - the Refrigerant Head
Pressure Rise Above the Opening Point
The forces that operate the valve are refrigerant head
pressure, water pressure, and spring pressure. These
forces oppose each other.
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.
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.

When the head pressure rises, and the refrigerant
pressure overcomes the spring force (pilot valve), the
valve begins to open (the disk lifts off of the seat). This
point is called the opening point.
The opening point is adjusted by increasing or
decreasing the spring force by using the adjustment
stem. If the head pressure continues to rise, the
refrigerant pressure further opens the valve until the
valve is fully open. The range from the point where the
valve lifts off the seat (the opening point) to the point
where the valve is fully open is called the throttling
range.
The throttling range is fixed and cannot be adjusted.
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
(plus any hysteresis) and pushes the disc off the seat,
allowing water to start flowing through the valve.
Anything above that point is head pressure rise above
the opening point. Typically, the opening point is
approximately 7 psi above the closing point.
Proper Valve Size
A properly sized valve meets the requirements of the
maximum water flow required yet functions at an
acceptable level when minimum flow is required (does
not water hammer, cut, or wire draw the seats and
seating discs). See Figure 3 and Figure 4 to select the
correct valve size for your application.
Use the following steps to help determine the
appropriate valve size for your application:
1. Locate the point where the valve is fully open on
the Refrigerant Head Pressure Rise Above Valve
Opening Point (y-axis).
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 Maximum Water Flow Available line
(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 Required for your
application (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
maximum flow requirement of the application.
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 through the condenser at
8 psid. 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 4, the correct valve for this
application is a 3-inch medium-pressure (160/260 psi),
non-corrosive, commercially constructed V43 Series
Valve. The maximum water flow that a 3-inch valve can
deliver (300 GPM) under the stated condition is slightly
greater than the maximum water flow required (300
GPM).
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).
Select the valve type from Table 5 through Table 7.

Installation and Initial Adjustment
1. Flush the lines to remove any foreign matter before
connecting the lines to the valve. See Servicing.
2. Screw each companion flange and gasket onto the
inlet and outlet water lines as indicated in
Figure 13. The inside of the companion flange is
threaded. See Table 10 for flange and gasket kit
information.
3. Mount the V43/V243 valves so that the water flow
follows in the direction indicated by the arrow on
the V43/V243 casting.
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.
5. Connect a 1/4-inch copper (or UltraCap) tube from
the bellows of the V43/V243 valves to the
refrigerant line as indicated in Figure 14. (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 indicated at the high side pressure
service gauge.
9. If necessary, adjust the operating head pressure as
instructed in the Valve Adjustment section.
Checkout Procedure
Note: Before operating equipment, always manually
flush the valve. See Servicing.
Before leaving the installation site, observe at least
three complete operating cycles (bellows open and
close) to verify that all components are functioning
properly.
Valve Adjustment
Make adjustments gradually. Adjust by 1/2 revolution
and wait for the system to stabilize after each
adjustment change. The throttling range (differential) is
not adjustable.
• To increase the opening point of the valve, turn the
adjusting screw (Figure 15, inset) inward, away
from main valve body (clockwise) as viewed from
the bottom up.
• To decrease the opening point, turn the adjusting
screw outward, toward the main valve body
(counterclockwise).
