2 Way Siamese Connection

forede®Siamese Connection functions as a core linking component in fire protection systems, primarily operating to merge multiple external water sources into a concentrated, high-performance supply for internal fire suppression systems. Its fundamental mechanism revolves around a dual-inlet converging design: two parallel inlets serve as interfaces for connecting external water supplies (such as fire truck hoses or hydrant lines). When activated, water from these separate sources enters the device simultaneously and converges within its internal channel, combining their flow rates and pressure. This merging process transforms dispersed, potentially low-pressure water streams into a unified high-pressure output, which is then delivered to the building's internal sprinkler or standpipe systems to meet the demands of large-scale or high-rise fire suppression. A key functional element supporting this process is the integrated clapper check valves. These valves act as one-way flow controllers: when both inlets are in use, they remain open to facilitate water convergence; if only one water source is connected, the valve corresponding to the unused inlet automatically closes to prevent backflow. This prevents water from reversing into idle supply lines, ensuring unidirectional flow and avoiding contamination or pressure loss in the active water source.
