Siamese

Siamese valves are essential components for fire department connections, allowing crews to combine multiple supply lines into a single, controlled water source for standpipes, sprinkler systems, and fire pumps. Designed to handle high-flow suppression operations, these valves feature durable brass or aluminum construction that withstands the demanding conditions of structural firefighting and prolonged pumping operations. Whether you're equipping a new FDC installation or replacing aging hardware at your station, reliable siamese valves ensure your water supply system performs when it matters most. Trusted brands offer UL/FM-approved options engineered for leak-free operation and long-term mission readiness.
