DESCRIPTION
The Apollo® MVB-LF (34BLF Series) Thermostatic Mixing Valves are designed to control and limit the volumes of cold and hot water required to deliver
mixed water at a predetermined temperature either from the “point of source” or “point of use” application for single or multiple fixtures. The valves are
built using “lead free*” materials and can be configured with several design features depending on your application. Now triple listed to ASSE 1017, 1069,
and 1070 and a minimum flow rate of 0.5gpm.
FEATU R ES
