Installation, Operation & Maintenance

SPRING-LOADED VACUUM BREAKER
MODEL K-060VB M1

The following is a step by step narrated description of the A.R.I. K-060VB M1 Spring-Loaded Vacuum
Breaker installation, operation and maintenance processes.

The  K-060VB  M1  Spring-Loaded  Vacuum  Breaker  is  a  normally  closed  full  bore  vacuum  breaker  which  is
designed to open fully to allow the intake of air into the pipeline or system when vacuum conditions occur,
thus protecting the pipeline.
Negative  pressure  (vacuum)  conditions  are  caused  by  sudden  shutoff  of  pumps,  pipe  ruptures  or  rapid
draining of the pipeline. The K-060VB M1 can be installed both on potable water lines and on wastewater
lines.

The  K-060VB  M1  Spring-Loaded  Vacuum  Breaker  is  designed  for  water  systems  that  operate  within  the
pressure and temperature framework of the model's specifications table. Please consult A.R.I. for products
designed for other wastewater or hazardous liquids systems.
