Valves are the core hub of industrial fluid control systems, widely used in petrochemicals, water conservancy and hydropower, energy storage, HVAC and sanitary ware. Their sealing performance, pressure strength and operational reliability bear directly on production safety, energy efficiency and public welfare. As Industry 4.0 deepens and smart manufacturing spreads, conventional manual inspection and standard general-purpose equipment can no longer meet the demand for precise, efficient and customised valve inspection. Professional valve inspection equipment has become the key support for companies building a quality defence and strengthening competitiveness.
Ouxun Intelligent Technology (Taizhou) Co., Ltd. has worked in this field for many years. Drawing on substantial technical accumulation, a professional R&D team and accurate market insight, it has built a full range of high-end valve inspection equipment, focusing on high-precision, intelligent machines that solve industry pain points through technical innovation — a one-stop intelligent valve inspection solution for valve manufacturers worldwide, leading the sector towards high-quality development.
Industry Pain Points: An Opportunity to Upgrade Valve Inspection Equipment
Valve manufacturing is moving towards finer, higher-end and larger-scale production, while inspection requirements continue to rise. Domestic standards such as GB/T 13927 and JB, and international specifications such as ISO 5208 and API 600, impose ever stricter requirements on sealing, flow, pressure and fatigue strength. Conventional inspection methods, however, still have major shortcomings that hold companies back.
First, insufficient accuracy. Manual inspection or general-purpose equipment with ordinary sensors produces large errors and cannot reach the ≤0.3% accuracy requirement, allowing non-conforming products onto the market and creating safety risks. Second, low efficiency. Manual procedures are cumbersome and data recording and report generation depend on manual collation, which cannot support batch inspection in volume production and constrains capacity. Third, poor adaptability. Valve specifications and process standards differ considerably between companies, so standardised equipment cannot handle non-standard valves or valves for special service conditions. Fourth, inadequate compliance. Some equipment does not fully conform to domestic and international standards, making it hard for products to pass CNAS, CE and similar certifications and affecting market access.
Against this background, valve inspection equipment offering high accuracy, automation, customisation and compliance is an inevitable industry trend. It also opens broad space for Ouxun to deepen its technology and expand its market — with years of accumulated expertise, Ouxun has become one of the benchmark companies in the field.
Technology-Driven: Ouxun Builds Its Core Competitiveness
As an established company in inspection equipment for valves, HVAC, sanitary ware and automotive components, Ouxun is rooted in Taizhou’s manufacturing base. With more than ten years of practical experience in valve inspection equipment, it has assembled a highly skilled and experienced R&D team and adheres to the principle of “technology at the core, service as the guide”. Its range covers pressure-reducing valve automatic setting machines, thermostatic mixing valve test benches, dynamic and static balancing valve test systems, impulse performance testers and more, covering the full spectrum of inspection needs — type dimensions, sealing performance, service life and fatigue strength — for valve companies of every kind.
High-Precision Technology as the Foundation of Quality
Accurate inspection is the core of valve quality control. Ouxun equipment uses imported high-precision sensors with an accuracy class well beyond 0.3%, capturing key parameters such as leak rate, pressure resistance and flow coefficient precisely. Leak rate detection reaches ≤10⁻⁶ mbar·L/s, fully meeting API 598 and other international requirements — a model of high-precision valve inspection equipment. At the same time, the equipment carries a PLC plus supervisory PC automatic acquisition and control system that collects, transmits and analyses data in real time, eliminating operator error and ensuring data that is authentic, accurate and traceable, giving companies a reliable basis for product optimisation and quality control.
Customised Solutions for Non-Standard Problems
Unlike the “one size fits all” standard equipment on the market, Ouxun recognises that inspection requirements differ between industries and companies, and follows a made-to-measure development philosophy: it designs dedicated equipment and solutions from the customer’s product drawings, production process and inspection standards. Whether it is a special high-temperature, high-pressure valve, a complex-shaped valve, or a requirement in energy storage or petrochemical service, the Ouxun technical team works directly with the customer through concept design, equipment development, installation and commissioning, and operator training, making sure the equipment fits the production requirement exactly and solving the “cannot measure, cannot measure accurately” problems of non-standard valves.
Intelligent Upgrades That Raise Throughput
To support batch inspection in volume production, Ouxun equipment has been fully upgraded with intelligence and a visual operator interface that is simple enough for a newcomer to learn quickly. It completes pressure regulation, testing, data acquisition and curve generation automatically without manual intervention, delivering three to five times the throughput of conventional manual equipment and cutting labour cost substantially. The equipment also generates standardised PDF test reports automatically, ready for product archiving, customer acceptance and certification submissions, further improving operational efficiency.
Full-Process Compliance Support for Market Access
All Ouxun inspection equipment is developed and designed strictly against national, industry and international standards, conforming fully to GB/T 13927, ISO 5208, API 600 and other specifications. The equipment is CE certified and backed by multiple patents and software copyrights, giving solid assurance that inspection results comply. With this technical strength, Ouxun has helped a number of large valve companies obtain CNAS national laboratory accreditation, opening market access and raising brand credibility and competitiveness — which is why so many companies choose Ouxun first.
Practice Empowers the Industry: Ouxun’s Strength and Responsibility
Ouxun has always held to the principle of “technology that lands, practice that empowers”, turning R&D results into real productivity. Its equipment is now widely used in valve manufacturing, energy storage, HVAC and sanitary ware, and petrochemicals, earning strong market recognition and a good reputation as a leading brand in the field.
One large valve manufacturer was struggling with a low pass rate, high rework cost and difficult certification. Ouxun built a complete custom inspection line for it: with high-precision equipment and intelligent control, the company could identify quality risks precisely and optimise its process. The pass rate rose from 96% to 99.8%, saving close to RMB 1 million a year, and the company passed CNAS accreditation, significantly strengthening its competitive position. There are many similar cases. Through quality equipment and professional solutions, Ouxun helps companies move from “simple manufacturing” to “quality manufacturing” and raises the quality level of the industry as a whole.
Beyond the products, Ouxun provides complete professional service: technical consultation, installation and commissioning, operator training and lifetime maintenance, with 7×24 response that resolves issues as they arise — genuine “consultation before sale, guidance during sale, assurance after sale”, making it an inspection partner companies can trust.
