AccuTEST In-Service Pressure Safety Valve Testing System
Introduction
AccuTEST is an advanced in-service testing system for Pressure Safety Valves (PSVs) developed by AccuTEST Systems USA, a global leader in valve testing technology. The system is designed to accurately verify PSV set pressure and functional performance without removing the valve from the process line or interrupting plant operations.
By applying a controlled external axial force to the valve spindle, AccuTEST determines the valve’s opening characteristics without increasing system pressure, allowing testing to be performed safely under actual operating conditions. This innovative approach eliminates the risks, downtime, and costs associated with conventional off-line and hydraulic testing methods.
The AccuTEST System is electrically motor-driven, providing precise force control, high repeatability, and clean operation, making it ideally suited for modern refineries, petrochemical plants, power generation facilities, and other critical process industries.
Key Benefits of AccuTEST
- Time & Cost Efficiency
Eliminates valve removal, workshop testing, transportation, and reinstallation, significantly reducing maintenance costs and manpower requirements.
- Controlled and Safe Test Methodology
Prevents over-pressurization of the process system by applying external mechanical force rather than increasing system pressure.
- Digital Data Recording & Traceability
Integrated digital data acquisition provides automated, traceable test reports for compliance, audits, and asset management.
- Predictive & Condition-Based Maintenance
Early identification of set pressure drift or mechanical degradation enables proactive maintenance planning and prevents unplanned failures.
- On-Line Testing Capability
Allows verification of PSV set pressure and functionality without plant shutdown, depressurization, or valve disassembly.
- Reduced Maintenance and Lifecycle Costs
Eliminates costs associated with valve removal, workshop testing, transportation, and reinstallation.
- No Plant Shutdown Required
PSV testing is conducted while the process remains pressurized and operational, eliminating production losses and downtime.
- Enhanced Safety
Testing is performed without increasing system pressure, preventing over-pressurization and reducing operational risk in accordance with API recommendations.
- High Accuracy & Repeatability
Electrical motor-driven actuation ensures controlled force application and reliable, repeatable test results.
