Stops with injection quills are commonly used to inject chemicals pumped by
metering pumps into tanks or headers. Popular chemicals where these
corporation stop valves are boiler chemicals and cooling water
chemicals, and other water process systems.
The injector quill extends into the center of the water
stream providing more uniform dispersion of injection chemical. Corporation
Stop Valve Products can be mounted to a “hot tap” which is installed without
having to drain the system. Corporation Stops are ideal for systems that never
shut down, since they can be inserted or removed without having to shut down the
system. Corporation stops are different then chemical injection quills .
Corporation Stop comes with a protection chain to prevent the injection
quill from being completely withdrawn before the corporation stop is
closed. This is a safety feature to protect against back pressure.
