The 4MDLG Series Deluge Valve with Alarm System is a precision-engineered fire protection valve designed for high-risk environments requiring immediate and uniform water discharge. Suitable for sizes ranging from 1 1/2" to 8", this valve features a robust construction using diverse materials such as Cast Iron (CI), Ductile Iron (DI), WCB, CF8, CF8M, and Bronze to withstand inlet pressures up to 16 kg/cm². Equipped with durable seals made of NBR or EPDM, and flanged ends, the valve is ideal for water and fire fighting applications. It operates by staying normally closed under regular conditions, instantly opening upon fire detection system activation to allow water flow to all system nozzles or sprinklers simultaneously, ensuring rapid fire suppression. Additionally, its integrated alarm system provides both audible and visual alerts to facilitate immediate response, enhancing operational safety in critical infrastructure. This valve is optimally suited for industrial plants, commercial complexes, and any high-risk facilities requiring stringent fire control measures.
