Pressure Reducing Control Valve, DN100, Ductile Cast Iron

The pressure reducing valve is designed for parallel water supply systems serving both firefighting and domestic needs. In the event of a fire, it prioritizes water flow to firefighting efforts by automatically cutting off the domestic supply, ensuring adequate water for emergency response. Once firefighting operations cease and water pressure stabilizes, the valve reopens to restore the domestic supply. This mechanism eliminates the need for a separate dedicated firefighting water pipeline, significantly reducing construction costs and water usage. Ideal for integrated water management, this valve ensures efficient and reliable water distribution in critical situations.
