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.
