Be Informed:
Check valves are vital components
of many systems. Their purpose is
simple: to prevent the reversal of
flow rather than stopping, starting, or
throttling flow. Reverse flow may be
merely a nuisance, or it can cause
severe damage to equipment con-
tamination of potable water supplies,
or hazardous conditions resulting
from the uncontrolled mixing of
various fluids in pipelines.
