Cast globe valves are supplied with a S-type body as standard, featuring a rising stem and handwheel. Flow is controlled by rotating the handwheel, which drives the stem and disc to move linearly, regulating or stopping flow within the pipeline. Globe valves are known for their long service life due to the absence of sliding friction between the disc and body seating surfaces.
