Description
The Danfoss 193B-1701 is a 1-1/4″ VTC511 series thermostatic mixing valve engineered for precise, reliable hot water temperature control in hydronic heating and domestic hot water systems. With a high flow coefficient (Cv) of 16.2, this valve is well-suited for medium-to-large commercial and residential hydronic applications where consistent mixed-water outlet temperatures and scalding protection are critical priorities.
The VTC511 series is a trusted solution from Danfoss — a global leader in HVAC and hydronic controls — delivering self-actuating, wax-element thermostatic technology that requires no external power source. The valve automatically blends hot and cold water supplies to maintain a stable, preset outlet temperature, protecting occupants from scalding while also preventing Legionella growth in stored water systems.
