Non Rising Stem Gate Valve
Non Rising Stem Gate Valve – Compact Design for Underground and Confined Space Applications
Non Rising Stem Gate Valves feature internal threading where the gate travels up and down the stem without stem rise, making them ideal for underground installations, buried pipelines, and confined industrial spaces across African water utilities and mining operations. This compact vertical profile eliminates the height requirements of rising stem designs, reducing vault depths and installation costs in space-constrained environments.
Serving African water distribution networks from Cairo to Cape Town, non-rising stem gate valves dominate DN 50 to DN 900 (2″ to 36″) buried service applications in Class 150-600 ratings. The handwheel rotates without vertical stem movement, enabling operation in shallow vaults and underground chambers common to municipal water systems, irrigation networks, and industrial buried pipelines throughout Africa and international markets.
