Deluge System Test & Drain Valve

The Deluge System Test and Drain Valve is an essential maintenance and inspection component that allows fire protection technicians to test deluge system operation and drain residual water from system piping following activation or testing — without requiring full system shutdown or disassembly. Viking test and drain valves incorporate a calibrated orifice that simulates the flow of a single open nozzle, allowing system flow and pressure performance to be verified during routine inspections. The integrated drain function ensures all water is safely removed from system piping after testing or discharge — preventing water accumulation, corrosion, and freeze damage in vulnerable areas. Compliant with NFPA 15 and UL listed for use in deluge and open-head suppression systems.
