Robertshaw 700-056 Gas Valve

The Honeywell Home AM101-US-1 (Union Sweat) is a high-performance proportional thermostatic mixing valve designed for precision temperature control in potable water systems and hydronic heating applications. Engineered with a lead-free brass body and a teflon-coated interior to mitigate scale buildup, this valve ensures long-term operational reliability in diverse water conditions. It features a locking adjustment cap to prevent unauthorized temperature tampering, providing a stable mixed water temperature range of 70°F to 145°F. With a maximum pressure rating of 150 psi and a high-flow Cv rating of 3.9, this ASSE 1017 certified mixing valve is ideal for increasing usable hot water capacity by allowing the water heater to be set at higher temperatures while protecting the end-user. The sweat union connections facilitate rapid installation and easy maintenance for contractors working on high-demand residential or light commercial plumbing projects.

• Enhanced Safety: Provides mechanical protection against scalding by maintaining constant outlet temperature despite fluctuations in supply pressure or temperature.
• System Efficiency: Minimizes heat loss and prevents Legionella growth by allowing the master water heater to operate at elevated temperatures.
• Durable Construction: The Teflon coating on the internal valve components significantly extends service life by resisting mineral deposits.
• Versatile Application: Suitable for domestic water, radiant floor heating, and larger-scale water distribution systems requiring precise tempering.
• ASME and ASSE Compliance: Meets strict lead-free requirements and industry standards for point-of-source water temperature control.

What is the maximum inlet temperature permitted for the AM101-US-1?
This valve is rated for a maximum hot inlet temperature of 212°F (100°C), making it compatible with high-temperature boiler loops and standard water heaters.

Is a check valve required for this installation?
While the AM-1 series relies on pressure balance, installing check valves on the cold and hot inlets is standard best practice to prevent thermal siphoning and cross-flow.

How does this valve help increase hot water capacity?
By mixing hot water with cold at the source, the AM101-US-1 allows you to store water at 140°F+ while delivering 120°F to the fixture, effectively increasing the available volume of tempered water.
