The Inlet Stop Valve is a key component in fire protection systems, designed to isolate and control water flow into critical equipment such as breeching inlets, dry risers, fire pump test connections, or sprinkler systems. It provides a reliable means of shutting off or regulating the inlet water supply, allowing for safe maintenance, testing, or emergency response.
Typically installed at the entry point of a system, this valve is built for durability, ease of operation, and high-pressure performance, making it suitable for use in commercial, industrial, and high-rise building applications.
