• 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 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 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.
