Level Controls at Work...
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.

INSTALLATION – TYPE 200
VACUUM BREAKER
• TodeterminewhichType200VacuumBreaker
you have, locate the part number on the
factory serial number label (See Information
Present on Type 200 section for location of
important information on vacuum breaker).
Then see Type 200 Specications section to
determine the performance and physical
characteristics of the vacuum breaker).
• Thevacuumbreakermustbeinstalledinthe
vertical position with its mounting connection
downward. A anged vessel mounting
connection must be a at surface to prevent
distortion of surfaces when the connection is
tight. A warped vessel mounting ange may
cause a leaky joint or break a cast iron Type
200 mounting ange.
• Eliminatevibration.Type200arenotsuitable
in installations where vibration exists.
• Before installing, be sure vacuum breaker
and piping are clean inside and free of scale,
chips, welding spatter, and foreign material.
Thoroughly blow out or ush pipe lines.
• Do not obscure factory serial number label
with paint.

• Type200 for the most partaremaintenance
free when sized and chosen properly for the
application. Maintain the uid pressure and
temperature within the limits of the vacuum
breaker (See Information Present on Type 200

• Openingsinadapterbodymustbe kept unblocked. The disc must be kept free of dirt
and debris. The disc must return freely to the
closed position if pushed away from the valve
body.
• Perform Seat Inspection during scheduled
maintenance periods. If necessary clean seat.
• Perform Opening Force Test during scheduled maintenance periods. If necessary adjust
opening force.
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 (ne) crocus cloth and a
general purpose degreasing solvent. Cloths or pads containing ultra ne 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 ngernail , 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 ngernail, 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.
