INSTALLATION – TYPE 200 VACUUM BREAKER
MAINTENANCE – TYPE 200 VACUUM BREAKER
• To determine which Type 200 Vacuum Breaker 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 Specifications
section to determine the performance and physical
characteristics of the vacuum breaker).
• The vacuum breaker must be installed in the vertical
position with its mounting connection downward.
A flanged vessel mounting connection must be a
flat surface to prevent distortion of surfaces when
the connection is tight. A warped vessel mounting
flange may cause a leaky joint or break a cast iron
Type 200 mounting flange.
• Eliminate vibration. Type 200 are not suitable in in-
stallations where vibration exists.
• Before installing, be sure vacuum breaker and pip-
ing are clean inside and free of scale, chips, welding
spatter, and foreign material. Thoroughly blow out
or flush pipe lines.
• Do not obscure factory serial number label with
paint.
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. The Type 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.
• Type 200 for the most part are maintenance free when sized and chosen properly for the application. Maintain the
fluid pressure and temperature within the limits of the vacuum breaker (See Information Present on Type 200 sec-
tion for location of important information on vacuum breaker and Type 200 Specifications section for additional
details).
• Openings in adapter body must be 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.
