The Fivalco fire protection valve range provides an extensive selection of flow control devices engineered for life safety, fire suppression, and building protection infrastructure. Featuring heavy-duty ductile and cast iron construction, the portfolio includes grooved, wafer, and flanged butterfly valves with integrated supervisory gear operators, resilient-seated OS&Y (Outside Screw & Yoke) and NRS (Non-Rising Stem) gate valves, and non-slam check valves—such as spring-loaded silent check, wafer double door, and swing check types designed to prevent backflow and water hammer. Supporting pressure ratings up to PN25 and 300 psi, along with corrosion-resistant brass/bronze auxiliary valves, air release valves, and strainers, these solutions are built to stringent international standards (including BS EN, DIN, and ANSI) to ensure rapid shut-off, unhindered full-bore throughput, and maximum system reliability under emergency conditions.
