DETERMINING THE SIZE OF THE MOST COST-EFFECTIVE

IN-LINE VALVE FOR PIPELINES PRESSURIZED

BY ELECTRIC POWER

The question is often asked as to what size of in-line valves SCS
recommends for any given pipe size in a pressurized irrigation system
receiving water from a pump. While most valve manufacturers say that
their valves will operate satisfactorily with velocities up to 15 feet
per second or more, this does not justify sizing the valve to
accommodate those velocities. To determine the most practical size valve
to install, one must consider the costs of ownership and operation that
the valve adds to the system.

We generally recommend that the valve diameter should be the same as the
pipe diameter for valves under about 12 inches in diameter. However,
there may be cases where a cost savings can be obtained by using a valve
that is smaller than the pipe diameter for these sizes. Conversely,
there may be larger sizes where it is more economical to use the same
size valve. Before approving a smaller valve than the main pipe
diameter, the designer should consider the effect on the rest of the
system. To accurately determine whether a cost saving can be obtained
requires an analysis of all annual costs associated with each valve size
under consideration. This usually amounts to a simple amortization of
the initial costs of the valve and appurtenances plus the increase in
annual power costs caused by the valve and appurtenances.

The annual cost of the valve and appurtenances is a matter of
determining the installed cost of the valve and cones, estimating a life
span and a typical interest rate, and multiplying the costs by an
appropriate amortization factor. A typical amortization table for a
20-year life is shown below.

A significant increase in power costs may occur as a result of the
increase in friction losses through the valves and reducing and
expanding cones. Compensation for these losses must be made by
increasing horsepower in the pump.

Using the head loss coefficient, K~n,~ to modify the velocity head,
V^2^/2g, for both the cones and the valve gives a procedure for finding
the head loss caused by the valve assembly that is consistent with that
used on ID-2l0---l57A and B, "Irrigation Pipeline Design Sheet". Unless
specific information is available, the following values for K~n~ are
recommended.

The velocity to be used in computing friction losses for each of these
appurtenances is the velocity through the valve; not the velocity in the
pipeline.

There is one aspect of power costs that is often overlooked when
calculating the cost of a valve. When a valve is in a lateral or a
sub-main that carries only a portion of the total flow being pumped, the
increase in head may need to be added to the cost of pumping the total
flow. For example, if a pump outflow is 1,000 gpm and the valve being
considered is in a sub-main carrying 500 gpm, then the increase in
annual power cost would be double (1,000/500) what it would be for the
flow in the sub-main only, if the required increase in head for the
valve will add directly to the head on the pump.

On the other hand, if the sub-main is not the critical line dictating
the horsepower for the pump, then the head loss through the valve may
not affect the operation of the system. In this case, the main
consideration is the cost of the valve and the limiting velocities to
prevent damage to the valve and other appurtenances. One must be careful
not to reduce the valve size too much so that the extra available head
is exceeded. As a rule of good practice, it is not recommended that the
valve be more than two sizes smaller than the pipe under any
circumstances.

The attached tables are included to show the average cost relationship
for the typical valve sizes used in SCS work. They illustrate the
procedures to be used in determining the most cost- effective valve
sizes to be used in typical irrigation pipelines. The flow rates, Q,
shown in column 3, are the flows with a velocity of 5 feet per second in
PVC pipe rated at 100 psi. Valve prices are based on prices found for
geared butterfly and gate valves shown in the 1993 Waterman Catalog.
Amortization factor for valve and cone prices is 0.1339 based on a
20-year life and 12% interest rates.

The annual power costs are based on an operating time, T, of 2,000
hours, a pump efficiency of 75% and a power rate, R, of \$0.04/KWH
applied to the following equation:

Annual Power Cost = [(Q,gpm) (T) (R) (Head Loss)]{.underline}

(Efficiency) (5300)

The tables show that, for the conditions described, a full size valve is
the most cost-effective from 6 inches through 12 inches for butterfly
valves and through 14 inches for gate valves. For larger pipe sizes, a
reduction of one size or more can be considered.

If valves cost substantially more or less than shown on the tables,
and/or power costs vary greatly from that shown, some changes may be
found in the general recommendations. However, the evidence shows that
we should continue to recommend full size valves for most of the work
done in SCS. A cost analysis similar to that shown should be done to
justify valve sizes other than recommended.
