Automatic Sprinkler System Equipment
Preaction Valve Assemblies
Project-configured valve assemblies for preaction sprinkler systems, available in flanged and grooved connection versions. Buyers can match the required nominal size, connection and assembly scope without relying on domestic model codes.
