Choosing test equipment starts with three questions: which product will be tested, which performance characteristics must be verified, and whether the equipment is intended for development testing or production inspection. For valve, HVAC, sanitary ware and automotive component manufacturers, matching the equipment to actual operating conditions is more useful than comparing equipment names and prices alone.
Ouxun Intelligent Technology (Taizhou) Co., Ltd. focuses on test equipment for valves and HVAC products. Its website covers valve, HVAC, sanitary ware, pipe and hose, air-tightness and automotive component testing. Manufacturers can discuss suitable equipment based on the product under test, test items and application.

1. Valve and HVAC testing: select equipment for flow, differential pressure and temperature control
Different valves and HVAC products require different tests. Balancing valves require attention to flow and differential-pressure behaviour, while thermostatic mixing valves require evaluation of outlet temperature and regulation. List the required tests before specifying the equipment.
The water flow test bench, also called a valve flow-capacity test bench, described on the Ouxun website is intended for water valves, static and dynamic balancing valves, and differential-pressure regulating valves. Test items include valve flow coefficients, balancing-valve flow coefficients at different scale settings, operating and control differential-pressure performance of differential-pressure valves, and dynamic regulation of dynamic balancing valves. Test specifications can be customised.

For domestic thermostatic mixing valves, underfloor-heating thermostatic mixing valves and thermostatic taps, Ouxun offers a thermostatic mixing valve test bench. Listed tests include outlet temperature, hot and cold water flow, mixed-water outlet flow, temperature adjustment sensitivity and cold-water supply failure testing. It can be configured for production or type testing, with the number of stations customised to requirements.

The website also lists automatic pressure-reducing valve adjustment machines, manifold test benches and thermostatic radiator valve performance test equipment. Manufacturers of these products can enquire about suitable configurations.

2. Sanitary ware testing: configure tests around performance and service life
Distinguish between taps, faucets, hoses, floor drains and drainage fittings when selecting test equipment. The name “comprehensive test bench” alone does not establish suitability.
Sanitary testing products listed on the Ouxun website include:
- Water valve and tap comprehensive performance test benches;
- Faucet endurance testers;
- Hose comprehensive performance test benches;
- Hose endurance and service-life test benches;
- Hose hot/cold and ageing test machines;
- Floor drain and drainage fitting comprehensive performance test benches;
- Anti-siphon performance test equipment.
Confirm test conditions, fixtures and acceptance requirements against the performance and endurance tests required for the actual product.

3. Pipe and hose testing: assess performance under changing pressure
For hoses, press fittings and push-fit fittings requiring pressure-cycle type tests, consider impulse performance test equipment.
Ouxun’s impulse performance test machine changes the internal pressure of the sample by switching rapidly between different pressure levels, assessing performance under defined conditions. Listed applications include hoses, press fittings and push-fit fittings. Test specifications can be customised.

For air-tightness verification of sanitary pipework, the website also lists an air-tightness test bench with an air compression system, pressure control module, test fixtures and control system. Specify test pressure, duration, leakage criteria and connection method during selection.

4. Automotive testing: thermal-management water valves and oil pumps need different solutions
Automotive component testing must be configured for the actual component. Thermal-management water valves and oil pumps differ in test objects, media and operating conditions; confirm equipment capability separately.
The thermal-management water valve test bench listed on the website supports type testing of thermal-management water valves. Listed items include static, dynamic and vacuum-pressure leakage tests, differential-pressure measurement and mass-flow-based testing. Specifications are customised to the customer’s product.

The oil pump comprehensive test bench is intended for automotive fuel pumps, hydraulic oil pumps and lubrication pumps. Listed applications include flow and pressure testing, speed control, sealing tests, temperature-rise testing, abnormal-noise detection and endurance/fatigue testing. The configuration must be confirmed for the pump under test.

5. Information to prepare before requesting a test-equipment proposal
To help match the equipment to your application, provide:
- Product information: product name, drawings, connection dimensions, samples and model range.
- Test items: flow, pressure, temperature, sealing or service-life characteristics to verify.
- Test conditions: medium, operating range, cycle count and acceptance criteria.
- Application: development validation, type testing or production inspection, including stations and cycle-time requirements.
- Acceptance basis: applicable standards and editions, customer specifications, data recording and report requirements.
This information forms the basis for equipment selection and technical discussions. The final test scope, measurement accuracy, automation level and deliverables must follow the technical proposal agreed by both parties.
