Custom-Built Solution for Electro-Hydraulic Proportional Valve Testing
Application
The hydraulic valve performance test system was custom-engineered for client to meet strict requirements for accuracy, reliability, and flexibility. It was developed to perform static performance testing on electro-hydraulic proportional valves, such as FIVA valve, ELFI valve,etc.,supporting both manufacturers and R&D labs and quality centers that demand precision testing and long-term durability.
Key Advantages
Advantage | Description |
High-Precision Control | Closed-loop PC control with 1 kHz sampling rate per channel-smooth, sawtooth-free curves |
Multi-Valve Compatibility | Test various valve sizes with interchangeable tooling – minimal changeover time |
Full Automation | One-click test execution: internal leakage, signal-flow, spool position, sensor calibration |
Real-Time Monitoring | Dynamic display of pressure, flow, temperature, input signal, and spool displacement |
Intelligent Safety | Multi-level alarms (overpressure, overtemperature, overflow, phase loss, low liquid) + emergency stop |
Data Traceability | Automatic test report generation (Word/Excel) – fully searchable history for audits |
Core Functions
The system supports a complete range of electro-hydraulic proportional valve tests:
Internal Leakage Test – Measures leakage at mechanical zero position under controlled temperature (42±1°C)
Signal-Flow Test – Maps input signal to flow output under rated pressure (up to 25 MPa)
Spool Position Signal Test – Records position sensor feedback across full stroke range (4–20 mA)
Position Sensor Calibration – Calibrates sensor zero and span using calibration rod tooling
