ESBE VTA Series Lead Free
Thermostatic Mixing Valves
temperatures at the source while maintaining
appropriate water temperatures out to the
xtures. With a higher temperature at the source,
the installation benets of the VTA series include:
• Additional volume of domestic hot water
through the thermostatic control of
temperature to the xtures
• Preventative measures to reduce growth
of Legionella by maintaining a high
temperature within the source and
safeguarding against scalding down stream
In the event there is a cold-water supply failure,
the hot water supply closes automatically.
The angle ow pattern of the ESBE VTA series
thermostatic mixing valves combine high quality
performance with remarkable ease of installation
and servicing.

Applications:
Specications:
The compact ESBE VTA series are Lead Free (LF)
thermostatic mixing valves designed for Point
of Source in domestic hot water distribution
systems and/or regulation of supply in hydronic
heating systems. The series of LF valves meet
the NSF/ANSI 372 standards for ‘lead free’
requirements, which took eect in January 2014.
The VTA series of valve replaces the Series 20 and
30MR styles of valves. The VTA series is available
in four temperature ranges:
• 85-120°F (30 – 49°C) (Domestic/ Hydronic)
• 95-140°F (35 – 60°C) (Domestic/ Hydronic)
• 70 -110°F (20 – 45°C) (Hydronic)
• 85-160°F (30 – 70°C) (Hydronic)
As a Point of Source for domestic hot water
application, the thermostatic control within
the VTA valve accommodates increased water
• Conforms to ASSE-1017*
• Anti-scald function*.
• Designed for mixing purposes.
• Long life and easy maintenance.
• Quiet operation.
• Compact design and lightweight.
• Snap-on cover for dirt protection and to
prevent unauthorized adjustment or
tampering.
• Cover label for recording setting
information including recorded outlet
temperature and date installed.
*Only ranges 85°-120°F and 95°-140°F meet ASSE-1017
standard.
