Pressure Rated Isolation Control for Water Distribution Networks
In water infrastructure projects, isolation clarity matters. Valve position must be visible, sealing must remain reliable, and pressure containment must align with specification. The Rising Stem ductile iron supplied by Dutco Tennant LLC is designed for controlled shut off across industrial and commercial pipelines.
Mostly in water distribution projects, the Ductile Iron Rising Stem Gate Valves are used for industrial and commercial applications.
Within municipal mains, pump stations, and process water lines, a correctly specified rising stem ductile iron assembly supports positive visual indication of open and closed position. The external stem movement confirms isolation status during inspection, while the ductile iron body structure provides measured strength under rated pressure classes. Epoxy coating supports extended surface protection in buried or exposed installations.
