Ouxun Intelligent Technology (Taizhou) Co., Ltd. was founded in 2015 and is headquartered in Taizhou, Zhejiang, known as China’s valve capital. Building on the region’s mature industrial base, the company works in depth in industrial automation and precision measurement equipment, focusing on the full cycle of R&D, manufacturing and sales. Over the years we have concentrated on core sectors — HVAC, data-centre liquid cooling, energy-storage thermal management and new energy vehicles — providing customers with reliable, durable liquid-cooling system test solutions that help them improve product quality and production efficiency.
With more than ten years of accumulated technology and a keen sense of market trends, we have independently developed a range of inspection equipment for critical liquid-cooling components: liquid-cooling valve test benches, dynamic balancing valve on-line inspection equipment, intelligent sensor test systems and leak detection test platforms. Our equipment is characterised by high accuracy, automation and visualisation, and can be flexibly customised to customer requirements. We already provide stable, efficient testing services to well-known HVAC brands, new energy vehicle manufacturers and data-centre infrastructure providers at home and abroad, and are widely recognised in the industry.
Core Products and Technology
Liquid-Cooling Valve Test Bench
Our flagship product, built specifically for performance testing of the various valves used in liquid cooling systems. It covers electronic pressure-independent control valves (EPIV), characterised control valves (CCV), flow proportional valves, ball valves, check valves and dynamic balancing valves, and serves factory testing, incoming inspection and development validation.
Technical features:
-
High-accuracy measurement: imported high-precision pressure sensors, flow meters and temperature sensors give a combined accuracy better than 0.3%, capturing flow characteristics, differential-pressure/flow curves, leak rate and shut-off pressure precisely, so the data is genuinely reliable.
-
PLC + supervisory PC automatic control: an industrial PLC working with supervisory PC software automates the whole test sequence. The operator sets the parameters and the machine completes pressurising, regulation, data acquisition and result judgement automatically, cutting manual intervention and operator error.
-
Visual operator interface: a 15-inch industrial touchscreen gives convenient, straightforward interaction, showing test curves, data and machine status in real time. Static testing, dynamic scanning and life testing modes support different test needs.
-
Automatic report generation: after testing, the system produces PDF/Excel reports containing data tables, characteristic curves and pass/fail results, with customisable templates for quality traceability, archiving and customer delivery.
-
Highly customised: dedicated non-standard design based on the customer’s valve type, size, test standard and interface requirements, matching test needs at development, production and inspection stages and solving individual pain points.
Dynamic Balancing Valve On-Line Inspection Equipment
For the dynamic balancing valves widely used in HVAC and liquid cooling systems — including static balancing valves, dynamic flow balancing valves and dynamic differential pressure balancing valves — we have developed dedicated on-line inspection equipment that performs flow-versus-differential-pressure testing directly on the production line, making sure every valve leaving the factory conforms to the design curve and product consistency is assured.
Key advantages:
-
Fast testing: a single valve is tested in under 30 seconds, matching the cycle time of high-volume production without slowing the line.
-
Multi-station design: dual or multi-station rotary tables can be specified to match capacity, so loading and testing run in parallel and overall throughput rises.
-
Adaptive clamping: pneumatic or hydraulic automatic clamping accommodates different valve sizes, making changeover quick and reducing line switchover cost.
Intelligent Sensor Test System
In a liquid cooling system, the accuracy and reliability of pressure, temperature, flow and leak sensors directly determine how well the system can be controlled. Our intelligent sensor test system performs multi-point calibration, linearity testing, response time testing and ageing screening on all types of sensor, ensuring performance meets specification on every count.
Technical highlights:
-
High-precision reference source: built-in professionally calibrated high-precision reference sensors make results traceable and verifiable, meeting industry metrology standards.
-
Multi-channel parallel testing: several sensors can be tested at once, raising throughput for batch sensor inspection.
-
Convenient data management: test data is stored automatically in a database supporting historical query, statistical analysis and SPC warnings, helping customers spot process anomalies early and improve quality stability.
Why Liquid Cooling Systems Need Professional Test Equipment
With the explosion of AI computing power and rising data-centre density, and the rapid spread of fast charging in new energy vehicles, liquid cooling has moved from an optional extra to a necessity for keeping equipment running reliably. The reliability of a liquid cooling system bears directly on the safe operation of core components such as IT equipment and battery packs. Valves, as the core of flow distribution and regulation in that system, have a performance that directly affects heat dissipation efficiency and energy consumption.
Take the EPIV (electronic pressure-independent control valve), a key component of liquid cooling systems. It must meet three core requirements: first, pressure independence — holding the set flow accurately regardless of system pressure fluctuation, ensuring stable cooling; second, high control accuracy, typically flow control error within ±1%; and third, zero-leakage shut-off, cutting off flow completely at zero load to avoid wasted energy.
The CCV (characterised control valve), for another example, needs an ideal equal-percentage flow characteristic for linear control of heat output, together with bubble-tight sealing to prevent leakage affecting system operation. These demanding performance targets must be verified by professional, rigorous testing before shipment to ensure the valve performs reliably in service. Ouxun’s test equipment exists precisely to meet this need — helping valve manufacturers, system integrators and end users validate product performance fully and keep liquid cooling systems running stably over the long term.
Applications
1. Data-Centre Liquid Cooling
In cold-plate and immersion liquid cooling and in the CDU (coolant distribution unit), valves are responsible for precise coolant distribution. Our test equipment is used for: EPIV/CCV factory testing, verifying flow control accuracy, pressure independence and leak rate precisely; complete CDU testing, simulating real operating conditions to check how the valves inside the CDU work together; and calibration of leak detection devices, verifying the sensitivity of leak sensors installed inside servers to keep data centres safe.
2. Energy-Storage Thermal Management
Energy storage systems — containerised storage in particular — place very high demands on thermal management; the liquid cooling system must remain stable across a wide temperature range. Our equipment tests proportional control valves, solenoid valves and balancing valves in storage liquid cooling systems under high and low temperature conditions, ensuring these components still work reliably under extreme conditions and keeping the storage system safe.
3. New Energy Vehicle Liquid Cooling
The battery, motor and electronic control systems of a new energy vehicle all rely on liquid cooling for efficient heat dissipation, directly affecting range and safety. We supply inspection equipment for battery-pack liquid cooling valves, water pumps and heat exchangers to new energy vehicle component suppliers, supporting quality control from product development through to volume production and helping them strengthen competitiveness.
4. HVAC
In building HVAC systems, EPIV, CCV and dynamic balancing valves are widely used in air handling units, fan coil units and other terminal equipment, directly affecting building energy performance and comfort. Our test equipment helps HVAC valve manufacturers improve product performance consistency and meet the strict energy control requirements of green buildings.
