Inspection, Assessment Domestic Track Records Main Client KHNP Project Name Turbine Valve Actuator Prediction Diagnostic Test Equipment Delivery Year 2018, 2023, 2024 Supplier Information • Future Automation Co. Turbine Valve Actuator Prediction Diagnostic Test Equipment (TVAT) Product Description: Actuator Prediction Diagnostic Solution It was previously impossible to diagnose the performance of the hydraulic actuator of a turbine valve—one of the core devices that control the amount of evaporator supplied to turbines in nuclear and thermal power generation—without separating it from the system. However, the current Performance Prediction Diagnostic Tester (TVAT) for Turbine Valve Actuators has been improved to make such diagnosis possible without disassembly. Specification: • Model: MR/TVAT-10-180 • Dimension: 1200*1100*1750mm • Weight: 700Kg • Pressure, Capacity: 5~200bar, 10lpm • Main Power: 380~480vac VLMS Product Description: Valve internal leakage can result from foreign materials between the valve body and seat, frequent operation damage, or fatigue cracks in the stem, packing, and welds. This leads to flow loss and reduced thermal efficiency, causing potential operational hazards. Leakage is detected through level checks, pressure tests, temperature/humidity measurements, and acoustic or probe inspections. Specification: • Continuously detects valve leakage in high-pressure, high-temperature systems using AE (Acoustic Emission) technology. • Piezoelectric sensors capture both low and highfrequency elastic waves and transmit them to the analysis system. • Features include real-time leak monitoring, 3D valve map display, 2-year data logging per valve, and early leak detection to prevent accidents and reduce maintenance costs. • Applicable to various valve types such as control, shutoff, safety, and check valves.
