Inlet Valve Flow Drifting and Fill Timeout? NL-WV-8 Inlet Solenoid Valve Flow & Response Test Bench Runs Eight Stations (pump performance test)

The inlet solenoid valve is the first gate on the water path of a washing machine, dishwasher, water purifier or instant water heater. A valve that runs low causes fill timeouts and error codes; one that runs high causes overflow and wrong detergent dosing; a slow response skews the timed-fill volume calculation. Incoming inspection that only checks open and closed cannot see any of it — the deviation surfaces on the finished appliance, where rework costs multiply.

What the NL-WV-8 flow & response test bench measures

• Eight stations cycling in parallel, with action counting and automatic failure detection
• Flow – pressure characteristic curves (the same water-circuit metering module used on our pump performance test benches)
• Opening and closing response time, actuation delay
• Sealing and hold-pressure leakage judgement
• Coil current, power consumption and temperature rise trend
• Consistency comparison across supply pressures and water temperatures, one-click report export

Applicable standards

GB 4706.1 (household appliances – general safety), IEC 60335-2-7 (washing machines), IEC 60335-2-5 (dishwashers), IEC 60730-2-8 (automatic electrical controls – mechanical requirements), plus customer-specific acceptance criteria.

Stations and throughput

Eight stations in parallel, designed for 24/7 running, so incoming lots can be sampled batch by batch or inspected 100% instead of relying on an operator flicking a valve by hand.
