Rising Stem Gate Valve – Outside Screw & Yoke Design for Visual Position Indication

Rising Stem Gate Valves feature OS&Y (Outside Screw and Yoke) construction where the stem rises and falls with valve operation, providing clear visual indication of valve position from a distance. This design is essential for above-ground installations across African refineries, power plants, and industrial facilities where operators need immediate visual confirmation of valve status without instrumentation.

From South African petrochemical complexes to Nigerian offshore platforms, rising stem gate valves serve DN 50 to DN 600 (2″ to 24″) applications in Class 150-900 ratings. The exposed stem threads provide instant position feedback—critical for safety protocols in African oil & gas operations and international projects requiring manual valve position verification during maintenance and emergency procedures. See our parent Gate Valve category for general isolation valve principles.
