Unyazi Speciality Services has announced a major expansion of its in-house valve testing and diagnostic infrastructure at its main service center in Cape Town. The company has invested in sophisticated testing equipment to meet the complex automation requirements of the industrial sector in Southern Africa, especially in the power generation, petrochemical refining and heavy mining industries.
The recent infrastructure upgrade enhances the facility’s ability to test a wider range of industrial valve products under extreme conditions. Now, the technical team is able to do rigorous evaluations on large-scale infrastructure components and even cater to valves up to fifty inches in diameter. The testing facility has also been upgraded to meet the extreme pressure requirements of ASME Class 4500 components. This allows engineers to do more complete hydrostatic testing, POP testing for safety relief valves, and sensitive seat leak testing with more accuracy and faster turnarounds. This ensures that secure seals are verified prior to equipment returning to service.
Central to this growth is the integration of advanced digital diagnostics. Today’s industrial plants rely on automated systems that demand accurate valve positioners and digital control systems. Unyazi Specialist Services has improved its ability to calibrate and service these digital components. Now, during the overhaul process, technicians can directly connect to smart instrumentation and obtain real-time diagnostic data. Through a thorough analysis of digital diagnostic feedback, the engineering team is able to identify specific mechanical issues, such as actuator lag, friction anomalies, and seat degradation. This type of analysis moves maintenance from reactive repair to preventative management. This allows plant managers to proactively address vulnerabilities before they escalate.
“The Technical Director of Unyazi Specialist Services stated that upgrades would impact operations.” “Their customers work in demanding industries where mechanical reliability is critical. Equipment failure causes immediate safety hazards and expensive production downtime. With their Cape Town facility’s increased high-pressure testing and digital diagnostic capabilities, facility managers have the data they need to make decisions about their equipment. “This means they can recondition and calibrate the valves to original factory specifications with complete certainty, ensuring that they will work exactly as they should when reinstalled.”
This improved internal service directly supports the company’s large field operations onsite. The Cape Town facility generates detailed diagnostic reports that help mobile technicians in planned site walkdowns as well as emergency interventions. A central location for rapid, high-volume testing can greatly reduce industrial plant downtime during large-scale maintenance events, such as shutdowns, turnarounds, and outages. The service center can quickly send faulty components found in the field, evaluate them correctly, repair them, and return them to the site, ensuring operational stability.
All new testing procedures and diagnostic protocols at the facility are in strict compliance with ISO 9001:2015 quality management standards. This means that all valves that come through the workshop meet international safety and performance standards. This expansion continues to enable Unyazi Specialist Services to provide technical support to maintain critical pipeline infrastructure through the region.
