ESBE VTA Series Lead Free Thermostatic Mixing Valves Datasheet
Applications:
Specifications:
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
• Conforms to ASSE-1017*
* Ranges 85°-120° F & 95°-140° F only
• 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
• Available connections:
• Threaded body (FNPT)
• Solder (Union connection)
• CPVC (Union connection)
• Maximum working pressure:
150 psi (10 bar) / CPVC: 80 psi (5.5 bar)
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.
• Maximum differential pressure between hot
and cold ports:
44 psi (3 bar)
• Maximum system differential pressure
between outlet and inlet ports:
72 psi (5 bar)
• Maximum hot water inlet temperature:
19 4°F (90°C)
• Minimum required flow for proper
temperature regulation:
• All valves except 1” NPT: 0.9 GPM
• 1“ NPT valve size: 2.0 GPM
• Up to a 50% glycol mixture for closed loop
