ESBE VTA Series Lead Free Thermostatic Mixing Valves Datasheet
Applications:
The compact ESBE VTA series are lead-free (LF) thermostatic mixing valves (TMV) 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.
The VTA series of valve replaces the legacy 20 Series and 30MR Series of valves. The VTA Series are available in four temperature ranges:
•85 to 120°F (30 to 49°C) (Domestic/ Hydronic)
•95 to 140°F (35 to 60°C) (Domestic/ Hydronic)
•70 to 110°F (20 to 45°C) (Hydronic)
•85 to 160°F (30 to 70°C) (Hydronic)
As a point of source for domestic hot water application, the thermostatic control within the VTA valve accommodates increased water
temperature at the source while maintaining appropriate water temperatures out to the fixtures. With a higher temperature at the source, the installation benefits of the VTA series include:
•Additional volume of domestic hot water to the fixtures at an appropriate regulated temperature
•Preventative measures to reduce
growth of Legionella by maintaining a high temperature within the source & safeguarding against scalding down stream
In the event there is a cold-water supply failure, the hot water supply closes automatically.
The angle flow pattern of the ESBE VTA series tmvs combine high quality performance with remarkable ease of installation and servicing.
