Spirax Sarco M10S/M10S2/M10S3/M10S4 FB/RB Ball Valves DN1/4"-DN21/2"

Spirax Sarco Spirax Sarco M10S three-section ball valve, as an isolation valve, not to be used as a regulating valve. Suitable for use with steam and other industrial fluids from vacuum to higher temperatures and pressures.The M10S can be serviced directly without removing it from the pipeline (threaded and welded models only).

Available Models

Note: In the naming convention, FB stands for full bore and RB stands for reduced bore.
