Lochinvar & A.O. Smith 100171922 Valve
The Lochinvar & A.O. Smith 100171922 is a heavy-duty 3-way control valve assembly engineered for precise hydronic flow management in high-capacity commercial boiler systems. This 2-inch NPT mixing and diverting valve features a robust brass body with plated brass trim, delivering a high 109 Cv flow coefficient. It utilizes an equal percentage flow characteristic on Port A to AB for accurate modulation and a linear flow profile on Port B to AB. Driven by a 24Vac non-spring return actuator, the 100171922 supports floating or two-position SPDT control signals, ensuring stable setpoint maintenance without hunting. The package includes closed nipples and flange hardware for direct integration into Lochinvar and A.O. Smith boiler loops. Designed for durability in demanding mechanical rooms, this direct coupled actuator configuration minimizes mechanical play and simplifies field installation for contractors maintaining large-scale thermal systems.
Key Benefits for Technicians:- High Flow Efficiency: The 109 Cv rating ensures minimal pressure drop across the 2-inch NPT ports in high-demand heating circuits.
- Precise Modulation: Equal percentage flow characteristics provide superior control at low-load conditions, preventing short-cycling.
- Simplified Wiring: The 24Vac floating/SPDT actuator integrates seamlessly with existing building automation systems (BAS) and boiler controllers.
- Reliable Construction: Plated brass trim and a rugged brass body resist mineral buildup and corrosion in closed-loop systems.
- Quick Installation: Includes essential mounting hardware, including nipples and flange, reducing total time on the job site.
Is the 100171922 actuator fail-safe?
No, this assembly utilizes a non-spring return actuator, meaning it will maintain its last position upon loss of power.
Can this valve be used for steam applications?
No, this specific brass ball valve assembly is designed for hydronic water and glycol solutions common in Lochinvar and A.O. Smith boiler systems.
What control signals are compatible with this unit?
This valve is designed for 24Vac floating (3-wire) or two-position SPDT control logic.
