The Anti‑Drain Valve Test Rig is engineered to test both inlet and outlet anti-drain valves of hydraulic filters per ISO 4548‑9. It conducts:
Test A: Basic anti-drain function (no reverse flow).
Test B: Secondary performance (sealing integrity under varied pressures).
Optional advanced procedures for deeper performance analysis.
Features an automated PLC-controlled system: adjustable pressure settings, precise flow regulation, and real-time monitoring via touchscreen. Test results and supplementary reports are generated automatically on PC software, conforming to ISO standards.
Standards Supported: ISO 4548‑9
Test Types: Test A (basic), Test B (performance), plus optional advanced
Pressure Range: 0–30 bar (adjustable)
Flow Control: Precision valve adjustments for inlet/outlet flow
Detection: Pressure sensors on both sides; flow meters
Automation: PLC with computer interface for real-time control
Data Output: Charted results, test summaries, and PDF reports
Construction: Industrial-grade frame with SS/Cu hydraulic circuit
Power: 230 V, 50 Hz supply
Used for verifying anti-drain valve function in hydraulic/oil filters per ISO 4548‑9. Essential for manufacturers, OEM quality assurance, and independent testing labs to validate valve integrity and performance.
