At YOUJI, we’re driven by a single mission: to provide the highest-quality, zero-tolerance leak inspection equipment for critical applications. This commitment to excellence has once again been recognized on an international level. We’re proud to announce that our main product lines—including the JWZ, JWT, and JLTD series of valve test benches—have successfully passed updated certifications for both the EU’s CE marking and the ISO9001 quality management system.

This dual certification is more than just a formality; it’s a testament to our continuous pursuit of superior quality and safety. For our clients in the petrochemical, smelting, nuclear power, fine chemicals, and infrastructure industries, this means even greater confidence in our equipment. These certifications are your assurance that our products meet the stringent requirements of a global market, providing the peace of mind that comes with using a world-class, rigorously tested solution.
Why This Matters for Your Operations
Your work demands precision and reliability, especially when dealing with high-pressure, high-stakes environments. We understand that a single leak is a failure, which is why we’ve designed our valve test benches to deliver flawless performance. This renewed certification validates our internal processes and our dedication to forward-thinking engineering.
We don’t just build equipment; we innovate. Our development is fueled by the feedback we receive from clients like you—from your experience using our products for 5 to 10 years. This real-world data allows us to continuously improve our technology, focusing on:
- Enhanced durability and reliability for long-term use.
- Cutting-edge technology that provides stable and reliable results.
- Long-term value, with a focus on high-quality materials and components that stand the test of time.

This commitment has helped our high-pressure intelligent testing systems become a preferred choice for high-end users worldwide, from new energy and nuclear power to marine engineering and fine chemicals.
With these certifications, we are solidifying our position as a leading global supplier of valve inspection equipment. This “passport” to the EU and other high-end markets allows us to expand our reach and bring our advanced solutions to even more customers who demand perfection.
As we look to the future, we will continue to uphold our core principles of “quality first, customer first.” Our journey is one of ongoing innovation, and we are excited to continue pushing the boundaries of what is possible in pipeline safety and valve inspection.
