This product is covered by one or more of the following patents: 6,431,011 and 6,463,807.
All GREYLINE insertion type meters can be installed and removed via
a 1” or larger full port ball valve without system shutdown. The terms
“Standard” and “Hot Tap” refer to the installation method of the
isolation valve kit only.
Standard Installation Hardware: For new construction or scheduled
shutdown; once kit is installed, the flow meter can be installed
or removed without system shutdown.
Hot Tap Installation Hardware: For applications which require the
access hole in the pipe to be drilled through the valve using a
wet tap drilling machine while the hydronic system is
pressurized and operating.
NOTE: Installation hardware materials vary greatly based on pipe
material, pipe size and standard vs. hot tap versions.
