Solenoid Valve Test Bench: Flow, Sealing, Response and Endurance Verified on One Fixture

The solenoid valve is the quietest component in an appliance water or gas circuit: it makes no sound, shows no light, and only announces a problem when the whole machine alarms. High cracking pressure blocks water supply at low line pressure; internal leakage prevents shut-off; slower response time corrupts programme timing; insufficient cycle life concentrates failures inside the warranty period. Sampling inspection and operator judgement cannot contain that risk.

What the NL-DFV-4 solenoid valve test bench measures

• Cracking / release pressure and switching consistency
• Internal leakage and external sealing (differential pressure or bubble method)
• Flow versus differential pressure curves, automatically acquired at multiple operating points
• Pick-up / drop-out response time, coil current, power and temperature rise
• Endurance testing with automatic cycle counting, automatic stop and failure recording

Applicable standards

GB/T 13927 (industrial valves – pressure testing), IEC 60730-2-8 (automatic electrical controls – water level valves), IEC 60335-2-5 (dishwashers) and the GB 4706 series of household appliance safety standards.

Stations and throughput

Four stations as standard, expandable to eight, each with independent pressure and temperature control and automatic step-by-step data logging — one machine covers both incoming inspection and type testing.
