3/4" Adjustable Thermostatic Mixing Valve, 100-145F, Lead-Free

Resideo Braukmann AM-1 3/4" Thermostatic Mixing Valve – Engineered for Safety and System Efficiency

The Resideo Braukmann AM-1 Series thermostatic mixing valve delivers precision temperature control and anti-scald protection in domestic hot water applications. Built for performance, this 3/4" valve combines robust construction with responsive thermal balancing to maintain outlet temperatures within safe parameters—even during system pressure or temperature fluctuations.

Ideal for hot water distribution, point-of-source mixing, or recirculating loop systems, the AM-1 is a proven solution for commercial, multifamily, and high-demand residential environments. Its nickel-plated brass body, internal EPDM seals, and tamper-resistant cap make it a long-lasting component that ensures code compliance and occupant safety.

Professional-Grade Benefits

• Thermostatic Regulation – Maintains stable outlet temperature despite changes in inlet pressure or temperature
• Fast Cold-Water Shutoff Response – Flow is rapidly reduced in the event of cold water supply failure to prevent scalding
• Lead-Free Construction – Complies with NSF 61 and lead content requirements under U.S. Safe Drinking Water Act
• Rugged, Serviceable Design – Nickel-plated forged brass body with Teflon-coated internals minimizes scaling and simplifies maintenance
• Factory-Set and Field-Adjustable – Adjustable outlet temperature range allows tailored system performance
• Mixing or Diverting Capability – Dual-purpose operation supports multiple configurations in hot water systems

Technical Specifications

• Connection Size: 3/4 inch
• Pressure Rating: 150 PSI max working pressure
• Temperature Range: 60°F to 212°F (operation), 120°F factory outlet setting
• Minimum Flow: 0.5 GPM
• Body Material: Nickel-plated brass
• Seal Material: EPDM
• Compliance: NSF/ANSI 61, ASSE 1017, CSA B125

Installation Considerations

This mixing valve is engineered for professional installation only. Proper pipe sizing, orientation, and system balancing are critical to valve performance. Installers must verify cold water shutoff response during commissioning and ensure that the valve is accessible for adjustment and maintenance. The AM-1 can be used in new systems or retrofitted to existing installations to meet code requirements and deliver consistent water temperatures.

Ideal Use Cases

• Domestic hot water supply systems in multifamily and light commercial buildings
• Tankless water heater mixing to achieve code-compliant outlet temperatures
• Boiler-fed mixing for radiant and combination DHW systems
• Recirculating loops where controlled return temperature is required

Performance You Can Trust

The Resideo Braukmann AM-1 is designed to provide years of trouble-free operation under demanding conditions. With its high thermal accuracy, durable materials, and field-serviceable components, it remains a go-to choice for contractors who demand both compliance and reliability.
