16. ABSTRACT
Four different Griswold flow control valves were tested and evaluated; they are anticipated for use on a pressurized sprinkler irrigation system. Tests were performed on each valve to observe discharge characteristics. Discharge accuracy was compared to the manufacturer's specifications. Debris conveyance was observed in two valves. Several kinds of debris were used and observed during the testing. Manufacturer's recommendat ions for screening debris were evaluated.

PURPOSE
At the request of the Bureau's Pacific Northwest Regional Office, tests were conducted
to evaluate the opera t ional characteristics and maintenance requi rements of several
Griswold flow control valves. The valves were proposed for the Yakima Project,
T ie ton Division in the Yakima-Tieton I r r igat ion District in Washington State. Tests
were performed to verify the manufacturer 's specifications of performance and
suitabili ty for a pressurized sprinkler irrigation application.
. °
INTRODUCTION
Flow control valves have been used on spr inkler i rr igat ion systems for many years.
However, their performance has not consistently satisfied the needs of both the user
a n d system operator. Griswold flow control valves - - Griswold Controls of Irvine,
California - - were tested to de termine the capabil i ty for delivering a constant flow
rate •within a +5 percent band over a design pressurecont ro l range.
The valves operate on the pr inciple of orifice control. They respond to pressure
different ial by using a calibrated spring that adjusts the orifice area exposed to the
flow which keeps the flow constant. Basic valve components are shown on figure 1.
These valves are available in four different ial pressure ranges (1.3 to 20, 2 to 32, 4 to 57,
and 8 to 128 l b / i n 2) and have flow rates ranging from 0.5 to 12,750 gal /min. Four valve
models were tested:
In the 8-* to 128-1b/in 2 range, two flow control valves were tested:
a 1 ½-inch threaded minivalve model (fig. 2) rated at 24 gal /min, and
a 3-inch threaded cluster model (fig. 3) with three flow cartridges:
m a 95 gal /min,
- - a 100 gal /min,
a 150 gal /min, and
having discharge ratings of: 100, 245, and 345 gal /min. i
In the 4- tO 57-1b/in z range, two flow control valves were tested:
a 3-inch threaded inl ine model (fig. 4) rated at 100 gal /min, and
a lO-inch flanged cluster model (fig. 5) with ten lO0-gal/min flow cartridges J
delivering a total flow of 1,000 gal/min.
In addi t ion to these discharge tests, the 3-inch threaded cluster valve and the 3-inch
threaded inl ine valve were tes t ed to obtain operat ional characteristics and to check
maintenance rqu i rements under different debris loads at a flow rate of 100 ga l /min at
50-1b/in z pressure d i f ferent ia l .
SUMMARY
1. Discharge tests on the 1]/2-inch threaded minivalve compared with the manu-
facturer 's specifications of a constant flow (+5 percent) over the 8- to 128-1b/in 2
dif ferent ia l pressure control range. The only major depar ture from acceptable values
were data below the +5.percent band by an addi t ional 28 percent at the low end of the
different ial pressure range (10 to 15 lb/in2).

2. Discharge tests on the 3-inch threaded cluster valve showed varying degrees of
comparison with tha t of the manufac turer - - depending on the flow cartridges used.
Flow cartridge combinat ions of 100 and 245 ga l /min compared well at the lower back
pressures appl ied to the valve. However, at 50- and 75-1b/in z back, pressures, most data
points fell above the +5-pe rcen t band. The 345-gal/min combina t ion was mostly
above the manufacturer ' s -4-5 percent band at all back pressures tested. An addit ive
error effect in the discharge was noticed when each addi t ional flow cartridge was
inserted in the valve to obtain a higher flow rate.
3. Discharge tests on the 3-inch threaded inl ine valve compared fairly well with the
manufacturer 's specified flow accuracy. About one-half the data points fell above the
+5-percent band at all back pressures tested for the upper half of the pressure control
range. ,,
4. Discharge tests results on the 10-inch flanged cluster valve indicate excellent
comparison with the manufacturer ' s flow accuracy. All data points fell wi thin the
+5-percent band throughout the pressure control range.
5. Debris tests performed on the 3-inch threaded cluster valve and the 3-inch threaded
inl ine valve aff irm the manufacturer ' s debris recommendations. Using a U.S.A.
s tandard sieve No. 20 ups t ream of the valve appears adequate for most debris loads.
One should consider smaller sieve sizes for an irr igat ion project location subject to
heavy silt or sand loads. The study showed the No. 20 sieve screened sand indicated a
discharge reduct ion of 15 percent. Sand particles also fouled and h indered movement
of the spring-controlled piston; consequently, the piston requi red cleaning to obtain
design discharge. P ine needles and aquatic weeds plugged orifice areas and flow rates
reduced as much as 70 percent. Test data from comparing the two 3-inch valve models
subjected to similar debris loads showed no significant differences. Maintenance was
not a problem on the 3-inch threaded cluster valve assembly; fouled or damaged flow
cartridges could easily be removed and cleaned or replaced.

TEST FACILITY
Testing was done at the Bureau of Reclamation's Hydraulic Laboratory in Denver,
Colorado. A high-head pump was used. Each of the four valves was placed in series
with the pump (fig. 6). Pressure measurements upstream and downstream of the test
valve were made with pressure" transducers as indicated on figure 6. Transducer
o u t p u t s were recorded on a chart recorder. The me thod for recording discharge
through the flow control valves depended on the flow rate magnitude.
• Low flow rates (24 and 100 gal/min) were measured with a weighing tank.
• • Midrange flows (245 and 345 gal/min) were measured with a calibrated orifice
meter.
• The high flow rate (1,000 gal /min) was measured using a calibrated 8-inch ventur i
meter.
Upstream and downstream pressures could be adjusted by throt t l ing gate valves on
ei ther side of the test valve.
Debris testing was done on the same piping arrangements as the discharge tests. A
standard 6-inch tee was modif ied to hold a 200- to 400-mL debris sample which was
injected into the flow (fig. 7) after a steady-state condit ion was achieved.

TESTING
Discharge Accuracy
1. T h e 1½-inch threaded minivalve was in the 8- to 128-1b/in 2 differential pressure
range and had a 24-gal/min flow cartridge. Tests were run at five back pressures
ranging from 0 to 75 lb / in 2 through the entire differential pressure range. Test results
are in'table 1 and on figure 8. Approximately two-thirds of the data points fell within
the band (-t-5 percent of design discharge) set by the manufacturer. The only major
discrepancy was in the lower end of the differential control range (10 to 15 lb/in2). In
this range, data were below the acceptable operating range where some points were
33 percent below design discharge.
2. The 3-inch threaded cluster valve was in the 8- to 128-1b/in 2 differential pressure
control range and had three flow cartridges that were tested at three design
:discharges; i.e., 100,245, and 345 gal/min. These test results are intables 2, 3, and 4 and
on figures 9, 10, and 11, respectively.
• One 100-gal/min flow cartridge and two blanks were used during the 100-gal/min
test. One-third of the data points fell above the +5-percent bancl. These points
occurred at back pressures of 50 and 75 lb / in 2 above 60-1b/in 2 pressure
differentials.
The 245-gal/min tests had two flow cartridges and one blank. Again, one-third of
the data points were above the +5-percent band. These points occurred at the
50-and 75-1b/in 2 back pressures but within the range of 25- to ll0-1b/in 2 pressure
differentials.
The 345-gal/min test had all three flow cartridges in place. About two-thirds of
the data points fell above the +5-percent band. These occurred in the 30- to
110-1b/in 2 pressure differential range at back pressures of 40, 50, and 75 lb / in 2.
5
3. The 3-inch threaded inl ine valve was in the 4- to 57-1b/in 2 differential pressure
control range and had a 100-gal/min design discharge. Test results are in table 5 and on
figure 12. One-half of the data points fell above the +5-percent band. Data indicate
flow th ro ugh the valve at a rate greater than design discharge at all back pressures
applied (12 to 60 lb / in 2) through differential pressures ranging from 20 to 57 lb / in 2.
4. The 10-inch flanged cluster valve was in the 4- to 57-1b/in 2 differential pressure
control range and was set at 1,000 gal/min. The valve contained ten 100-gal/min flow
cartridges and one blank. Test results are in table 6 and on figure 13. All data points
fell within the +5-percent band.
Debris Tests
Because of the operating concept of the Griswold f lo~ control valve (adjustable orifice
area), debris is a serious concern. The manufacture~ recommends screening water to i
the valve with at least a U.S.A. s tandard sieve No. 20. Debris tests were run to verify the
No. 20 sieve and to observe how the valve functions when larger debris enters it.
Debris tests were done on the 3-inch threaded cluster and the 3-inch threaded inl ine
valves at a steady state of 100-1b/in 2 pressure upstream of the valve and 50 lb / in 2
downstream of the valve. A 100-gal/min flow cartridge was in place in each valve. In
the cluster valve, the 100-gal/min flow cartridge Waspositioned below and slightly off
center of the incoming supply line. A debris sample of 250 to 400 mL was placed in the
injection chamber and, when steady-state operat ing condit ions were obta ined it was
injected into the flow. After injection, pressure and discharge were moni tored over a
durat ion of 20 to 30 minutes.
Several types of debris samples were used in the testing. Sand was tested for several
sieve sizes; i.e., U.S.A. standard sieve Nos. 6, 10, 14, and 20 (0.141-, 0.065-, 0.0331-, and
0.0168-inch openings), respectively. Dry pine needles in about 1-inch lengths were
tested and some debris collected from traveling water screens in the project area. The
latter debris consisted mostly of moss and Other aquatic weeds.

All sand sizes were tested through the 3-inch threaded cluster valve; results are in
table 7 and on figure 14. Clogging of the orifice areas is evident as shown on figure 15.
However, clogging did not seem to be the major problem. When the flow cartridge was
cleaned and replaced in between test runs, about 15-percent decline in maximum
discharge was noted. This temporary loss in flow rate was due to fouling of the
spring-loaded piston. Apparently, small sand particles lodged between the movable
p i s t on and the valve body and restricted piston movement. After more thorough
cleaning, the valve operated at design discharge (before debris injection).
In addi t ion to the sand sizes tested, dry pine needles and field collected debris were
tested in the 3-inch threaded cluster valve. Results are in table 7 and on figure 14.
Major port ions of the orifice areas were plugged by those two debris (fig. 16). I t is
noted this material was unscreened and tested strictly to observe operation.
Several tests were run on the 3-inch threaded inl ine valve. Sand passing through a
No. 20 sieve, dry pine needles, and field-collected debris were each tested in this valve.
Results are in table 8 and on figure 17. Nearly identical results were found for the two
3-inch valves tested. Flow rate reduct ion was slightly less th rough the 3-inch threaded
cluster valve (versus the 3-inch threaded inl ine valve), probably due to the increased
turbulence near the flow cartridge caused by the larger chamber area (fig. 18).
