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.

ESBE VTA Series Lead Free Thermostatic Mixing Valves Datasheet Domestic Hot Water Sizing: Typical Piping: For domestic hot water systems the VTA series can be sized based on the number of fixture units the valve will supply. Table 1. Fixture Units Valve selection process: 1. Determine the type and number of fixtures to be supplied by the mixing valve. 2. Assign fixture units from Table 1 for each fixture type. 3. Add the total number of fixture units. 4.
