company strategy
Naledi Trading (Pty) Ltd supplies, installs and commissions, Auma and Sipos electric valve actuators, various instrumentation and control systems for valve automation in all types of industry.
In the world of industries there is a constant motion. In pipelines and tubes, in tanks and channels, water or oil, steam or gas – nothing remains in one place for long, motion and flow or the driving forces of any system or plant, however large or small.
This motion, however, is not left to chance, it is linked to logical operational processes which are controlled and regulated. Valves open and close or control the pressure according to the plant design. Electric actuators operating gate, glove, ball and butterfly valves together with various instrumentation determine the rhythm of flow. They are integrated into control centres or monitoring consoles, or they rely on their own intelligent electronics.
