Gases or vapor
are compressible, and if not vented cause what
is known as vapor lock in your metering pump
and the system, causing the metering pump to
malfunction and in most cases the pump to stop
discharging chemical to the system.
The valve is designed to allow for the venting
of gases and condensed vapor back to the feed
tank, which improves priming on initial startups
and continuous trouble free operation while
working under pressure.
The valve when in operation vents gases, vapor
and a small amount of liquid, which is the same
as the chemical being pumped. This discharge
must be returned through hard piping or tubing
back to tank, to prevent personnel or equipment
from coming in contact with the vented corrosive
liquid.
