How to use
Install the FERRO KM11 valve into a prepared section of 1/2" threaded pipe using appropriate sealing material on the threads and tightening tools to achieve a leak-free connection.

Verify system pressure and temperature limits of the installation before first use and perform a leak test after installation.
