Stepper Motor Water Valves - 910 Models
Making true commercial-grade water heaters involves more than just redesigning our heat exchangers—every
internal component has to measure up to A. O. Smith’s commercial standards. Just like our advanced heat exchangers,
the longevity and functionality of components such as our water valves and flow sensors are also of great importance.
Our commercial-grade water heaters (510 and 540), as well as our commercial water heaters (CT-199 and 910)
feature a bypass and flow adjustment valve, which not only provide the optimal control and precision essential for
commercial usage, but also offer the durability needed to handle tough, high-volume conditions.

Water Flow
Condensation can build up over time in any heat exchanger, causing damage and premature leaks. A. O. Smith’s
commercial models (910 series) include condensation reduction features that safeguard against these types of
damaging effects.
Better Water Pathway Design
By redesigning and redirecting the flow of water, the temperature of the heat exchanger drum and finned coils
stay elevated above dew point, making it much more difficult for condensation to build.
Fin Pitch
By widening the pitch of the heat exchanger fins, not only do we improve durability by reducing occurrences
of blockage, we also maintain higher temperatures on the upper finned coils. Keeping these coils at elevated
temperatures reduces the likelihood of condensation buildup.
