The 2026 Shanghai International Water Expo closed at the National Exhibition and Convention Center on 9 June. Over the three-day event, Ouxun Intelligent Technology from Taizhou presented its new generation of valve inspection equipment. Rather than flashy virtual demonstrations, the team ran live, pressurised measurements on the stand, showing visitors real sealing and strength data under actual working conditions.
Why Valve Inspection Equipment Matters
In water supply, drainage, fire protection and industrial fluid systems, valves are the core components that control media flow. A single gate valve with failed sealing can drive maintenance costs across an entire pipeline sharply upward. Whether it is final QC at a valve manufacturer or on-site sampling during project acceptance, a stable and accurate inspection system directly determines pass rates and engineering safety.
The equipment Ouxun brought to the show covered the following live test scenarios:
-
Valve sealing performance: detecting micro-leakage under high differential pressure, with leak-detection sensitivity at the top of the industry.
-
Body strength pressure test: bi-directional over-pressure hold on body and bonnet to verify structural reliability.
-
Multi-station parallel testing: simultaneous testing of valves in different sizes and pressure classes to raise line throughput.
Technicians demonstrated with a DN100 resilient-seated gate valve. The machine automatically completed the full sequence — clamping, water filling, pressurising, holding and relieving — with data shown live on the LCD panel. Any abnormal fluctuation in the pressure curve triggered an automatic reject and alarm. A valve factory owner from Shandong commented during the demo: “This is exactly what we need — equipment that does not depend on the operator and gives straightforward data.”
From Taizhou to Shanghai: Practical Engineering for Real QC Pain Points
Ouxun Intelligent Technology (Taizhou) Co., Ltd. is rooted in the valve manufacturing belt and knows the everyday problems on the inspection floor: hiring is hard, training takes months, and manual readings are error-prone. The company’s development principle is clear — let the machine handle the tedious pressurising, timing and judgement steps.
To that end, the equipment includes the following practical features:
-
Simple operator interface: large touchscreen control with common test standards preloaded for one-touch recall.
-
Rigid sealing fixtures: custom quick-seal heads for flanged, wafer and grooved valve connections, cutting bolt removal time.
-
Power-loss protection and data traceability: valid data already acquired survives a sudden power cut, and can be logged and turned into a test report automatically.
None of this is glamorous, but it removes the real bottlenecks on the production line. At the stand, a technical lead from a Nantong drainage engineering firm, after repeatedly confirming that the hold pressure did not drift, exchanged technical proposals on the spot and asked for a custom solution for large-diameter butterfly valves.
In Closing
Exhibiting at the Shanghai Water Expo was, for Ouxun, not just a product showcase but a concentrated conversation with front-line users. We collected concrete feedback on pressure ratings, communication interfaces and explosion-proof requirements across different industries — all of which goes onto the next iteration list.
