MODEL MVB / 34B Series
DUAL PURPOSE ASSE MIXING VALVE
DESCRIPTION
The Apollo® Model “MVB” 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.
FEATURES
Highest capacity device that meets ASSE 1070 for Point of Use applications
Superior thermostatic element technology for optimum accuracy and
reliability.
Integral strainers and check valves to provide protection against cross-flow.
Tamper resistant locking cap design
Maximum temperature setting adjustment
Meets the requirements of Federal EPA Safe Drinking Water Act
Instantaneous cold or hot water supply failure shut-off protection
Multiple connection options to fit your specific needs

FLOW CURVES
Flow curve is based on the following: Cold and hot water inlet pressures at 45 psig; cold water supply temperature at 55 ±5 °F; hot water supply
temperature at 140 ±5 °F, and mixed water temperature at 105 ±5 °F. FLOWRATES MAY VARY DEPENDING ON ACTUAL SYSTEM OPERATING
CONDITIONS.
TYPICAL APPLICATIONS
The Apollo® Model “MVB” is ideal for supplying and maintaining tempered water to sinks, baths, showers as well as
individual temperature control to tubs or lavatories in residential, commercial or institutional applications.
