Armstrong International C4427-2 Valve

Armstrong International C4427-2 is a 3/4-inch NPT cast-iron strainer with a blowdown connection. The body is cast iron and houses a 0.045-inch perforated stainless-steel screen to trap particulates while preserving flow. With 3/4" NPT threaded connections, it installs inline in piping systems and provides a dedicated blowdown outlet for purging accumulated debris, helping maintain steady flow and protect downstream equipment. This Armstrong part is designed for inline filtration in general service lines where solids must be removed before entering valves, pumps, or other components. The combination of a durable cast-iron body and a corrosion-resistant stainless-steel screen delivers long-term service in mechanical and process installations where reliable particulate filtration is required.
