Globe Valve

Globe Valve

African Valve is a prominent Globe Valve Manufacturer in South Africa, specializing in high-integrity flow regulation solutions. Our globe valves are engineered for precise throttling and tight shut-off in applications requiring frequent flow modulation. With their linear motion design and robust sealing, they are ideal for use in steam, oil, chemical, and high-pressure systems.

Function & Working

A globe valve regulates flow by lifting a disc off a seat with a linear stem movement. This movement allows for fine control of flow rates, especially in throttling applications. The perpendicular flow path ensures efficient regulation, and the disc-to-seat contact provides reliable leak-tight sealing.
