Client Background
Zhejiang Jingzhen Fluid Technology Co Ltd is a prominent manufacturer and supplier in the fluid control industry. To meet the strict quality standards of the market and expand their testing capabilities, they needed to upgrade their factory inspection lines with reliable and highly automated valve testing equipment.
The Challenge
The client faced a complex testing scenario. On one hand, they needed to test massive industrial cylindrical valves with diameters ranging from DN700 to DN1200. Traditional testing benches often struggle with the length variations of these huge valves and require excessive safety measures for high pressure testing. On the other hand, they also required a highly automated testing solution for standard sized flanged valves from DN15 to DN100, which had to comply with stringent international and national standards.
Our Solution
To solve their challenges, we provided a dual equipment solution featuring the YFJX-DN1200 and the YFJX-LQ100.
For the ultra large valves, we supplied the YFJX-DN1200 Claw Type Valve Test Bench. This is a specialized split ring embracing hydraulic test device. It utilizes six sets of synchronous hydraulic claw mechanisms to lock the middle of the valve body. This innovative design is not constrained by the length of the valve. It is perfectly suitable for testing gate valves, globe valves, ball valves, and check valves with flange connections from DN700 to DN1200. Please note that this equipment is specifically designed for these types and is not suitable for testing butterfly valves. It features a water and gas dual channel system. It can sequentially perform the shell water pressure strength test and the bidirectional gas tightness test of the valve seat. The water immersion leak detection method ensures high accuracy and efficiency. The split layout design makes it incredibly easy to adapt to various workshop spaces, while multiple safety protections guarantee secure high pressure operations.
For the standard valves, we provided the YFJX-LQ100 Hydraulic Valve Test Bench. Manufactured strictly under the ISO9001 quality management system, this machine fully complies with GB/T13927-2022, GB/T26480-2011, and API 598 standards. It integrates hydraulics, mechanics, electricals, and medium storage circulation into one compact unit. It features a reasonable structure, complete functions, stable performance, and a high degree of automation. It is perfectly designed for testing the high, medium, and low pressure sealing and strength performance of straight flanged valves with nominal diameters from DN15 to DN100mm.
The Cooperation Process
During early 2024, the client contacted us for a comprehensive valve testing solution. Our engineering team carefully analyzed their factory layout and testing requirements. We recommended the combination of the heavy duty YFJX-DN1200 and the versatile YFJX-LQ100. We provided detailed technical drawings, safety operation guidelines, and arranged a smooth delivery of both units to their facility.
Results and Client Feedback
The two valve test benches have been successfully installed and are running flawlessly in the client's factory. The YFJX-DN1200 has greatly simplified their large scale valve testing process, eliminating the length constraints and ensuring ultimate safety with its six hydraulic claws and water immersion testing. Meanwhile, the YFJX-LQ100 provides rapid, automated, and highly accurate testing for their smaller valves. The client is extremely satisfied with the robust build quality, the precise test results, and the excellent adaptability of both machines. These machines are now highly valued assets for their manufacturing and maintenance operations.
