Level Controls - IOM 200 VACUUM BREAKER 200__IOM_RevC_0618
The following is a typical example of a tank filling/deaerator application using properly sized, selected, and maintained Warren
Controls Level Controls. Demand for water reduces the liquid level in the tank. The [A] 377 Float Cage opens the [B] 322L or 326L
Lever Valve to supply intake water to the tank. When the water reaches the desired level the float cage closes the lever valve
to accurately maintain the liquid at the desired level. Deaerators, tanks with steam blankets, produce additional liquid as
the steam condenses. The [C] 313 Overflow Trap traps and relieves this condensate through its internal pilot without
the steam blanket escaping. Overflow can occur if the water entering the tank exceeds its capacity. The 313 Overflow
Trap relieves the overflow through its internal single seated main stage valve. Falling liquid levels and condensing steam
can cause a vacuum that can damage the tank. The [D] Type 200 Vacuum Breaker opens to admit outside air to relieve the
vacuum in the tank. Warren Controls Level Controls are also used on boiler make-up water tanks and many other storage tank
applications.

OPERATION – TYPE 200 VACUUM BREAKER
 When no vacuum is present the vessel pressure acts on the vacuum breaker’s discholder pressing the disc into the seat
sealing the tank’s/ pipeline’s contents inside. When the vessel pressure drops below atmospheric pressure a vacuum forms.
The atmospheric pressure then acts on the discholder to overcome the force of the vacuum breaker’s spring. The seat and
disc separate admitting outside air. TheType 200 Vacuum Breaker opens gradually to admit outside air to relieve the vacuum
in the tank/ pipeline. The Type 200 Vacuum Breaker cannot be preset to open at a particular setpoint.

SEAT INSPECTION AND CLEANING PROCEDURE
1 ) Remove line or tank pressure and isolate vacuum breaker. (It is recommended that the vacuum breaker be removed from the piping or
tank for the seat inspection and cleaning procedure. It is recommended that you have an Inspection Kit on hand before beginning the
procedure.)
2) Remove nuts and bolts fastening valve body to adapter body.
3) Remove valve body from adapter body.
4) Remove capscrews from spring chamber.
5) Remove spring chamber from valve body.
6) Remove jamnuts from stem. Be careful, spring is preloaded.
7) Remove spring button.
8) For vacuum breakers with single spring remove spring. For vacuum breakers with dual springs remove outer and inner springs.
9) Remove disc and stem assembly from valve body.
10) Clean gasket surfaces on valve body and adapter body.
11) Inspect the integral seat or seat ring in the valve body. The integral seat or seat ring must be clean and free from deposits, scratches, or
other damage. If deposits are present clean the seat with red (fine) crocus cloth and a general purpose degreasing solvent. Cloths or
pads containing ultra fine silicon carbide such as a Scotch-Brite Ultra Fine Hand Pad or Norton Bear-Tex Clean & Finish Pad are also suitable
for cleaning the seat. Clean the seat with a circumferential motion around its diameter not with a longitudinal motion across its length.
For vacuum breakers with an integral seat, if after polishing the seat, you can still detect deposits, scratches, or other damage with your
fingernail , then replace the vacuum breaker. For vacuum breakers with a replaceable seat ring, if after polishing the seat, you can still
detect deposits, scratches, or other damage with your fingernail, then replace the seat ring. For vacuum breakers with an integral seat,
after cleaning, a light coat of primer may be applied to protect the seat.
12) Install disc and stem assembly in valve body.
13) For vacuum breakers with single spring, install spring over stem and center spring over pilot on valve body. For vacuum breakers with
dual springs, install inner spring over stem. Install outer spring over stem and inner spring. Center outer spring over pilot on valve body.
14) Install spring button on stem. Watch orientation. Center spring(s) over pilot(s) on spring button.
15) Install jamnuts on stem. DO NOT tighten until opening force is adjusted see following page.
16) Install new gasket on adapter body.
17) Install valve body on adapter body.
18) Install bolts through holes in adapter body and valve body. Install nuts on bolts. Tighten nuts and bolts in increments in an alternating
pattern.
19) Complete steps 4 thru 10 of Opening Force Adjustment Procedure.

2) Remove capscrews from spring chamber.
3) Remove spring chamber from valve body.
4) Apply water to cover top of disc.
5) Refer to table below. Apply opening force to end of stem using dead weights. The seat must open enough that it will not
hold water applied above the disc retainer. The disc must return to contact the seat when the weight is removed.
OPENING FORCE ADJUSTMENT PROCEDURE
1) Remove line or tank pressure and isolate vacuum breaker.
(It is recommended that the vacuum breaker be removed from the piping or tank for the adjustment procedure)
2) Remove capscrews from spring chamber.
3) Remove spring chamber from valve body.
4) Loosen jamnuts on stem until disc is not in contact with seat.
5) Tighten lower jamnut against spring button until disc remains in contact with seat.
6) Apply water to cover top of disc.
7) Set spring opening force. Refer to table in Opening Force Test Procedure. Apply opening force to end of stem using dead
weights. Adjust the positionof the lower jamnut on the stem so the seast opens enough that it will not hold water applied
above the disc retainer; and the disc returns to contact the seat when the weight is removed.
8) Tighten upper jamnut against lower jamnut.
9) Install spring chamber on valve body.
10) Install capscrews through holes in spring chamber. Tighten capscrews to secure spring chamber to valve body.
OVERHAUL
Rebuilding of the vacuum breaker should not be necessary under normal operating conditions. Should the vacuum breaker
become worn or damaged, parts kits are available. See Parts/ Overhaul.

INFORMATION PRESENT ON TYPE 200 VACUUM BREAKER
There is information present on each vacuum breaker ranging in importance from the part number and serial number to the
color of the paint and casting numbers. This information is important for identifying the vacuum breaker, installing it correctly,
and obtaining parts. An example of the current factory serial number label used on Type 200 vacuum breakers is shown
here. The accompanying table identifies the information present and where to find it on the vacuum breaker. There may also
be other casting numbers and foundry marks present that do not provide useful information. Customer specific tagging may
also present. The labels or plates used, and information present, on Warren Controls other product lines or older vacuum
breakers may be different, contact the factory for details.

APPLICATION:
Falling liquid levels and condensing steam can cause a vacuum
that can damage a tank. The Type 200 Vacuum Breaker opens

Damaged or worn parts can decrease performance and shorten the life of the vacuum breaker.
A damaged or worn gasket can cause external leakage and damage to surrounding equipment.
A damaged or worn spring can result in a vacuum breaker that does not close when the vacuum in a tank is relieved allowing the tank’s
contents to escape and damage surrounding equipment, and can also cause damage to the stem.
A damaged or worn stem can result in a vacuum breaker that does not open to relieve a vacuum in a tank or close when the vacuum is
relieved allowing the contents to escape and damage surrounding equipment, and can also cause damage to the stem guide.
A damaged or worn stem guide can result in a vacuum breaker that does not open to relieve a vacuum in a tank or close when the
vacuum is relieved allowing the contents to escape and damage surrounding equipment, and can also cause damage to the stem.
A damaged or worn connecting pin, disc, disc retainer, or disc holder can cause external leakage resulting in the loss of the contents
from the tank and damage to surrounding equipment, and can also cause damage to surrounding parts inside the vacuum breaker.
A damaged or worn integral seat or seat ring can cause external leakage resulting in the loss of the contents from the tank and damage
to surrounding equipment, and can also cause damage to the disc and disc holder.
Two different parts kits are available. An Inspection kit is available to allow a vacuum breaker to be opened to inspect its internal parts. A
rebuild kit is available to allow a vacuum breaker to be overhauled. Please provide serial number to get the correct kit part numbers.
