2025/3 – Nether Seal Shanghai Manufacturing Center Successfully Produced 12’’2500LB Certified valves

On March 15, 2025, a batch of RSBV certified valves produced by the Nether Seal Shanghai Manufacturing Center officially completed all assembly and testing processes. Their performance reached an internationally leading level, with sealing performance meeting the ISO 5208 Class A standard and achieving outstanding zero-leakage performance. This not only reflects technological prowess but also marks a significant step forward for Nether Seal’s Shanghai Manufacturing Center.

In this cert valve production, four cert valves were manufactured, namely one R3FC1500, one R10FC1500, and two R12FC2500. Among them, the 12-inch full-bore ball valve is particularly noteworthy as it broke the previous maximum pressure class record for 12-inch ball valves produced by our company, achieving a new technological breakthrough. This accomplishment would not have been possible without the diligent efforts and unwavering dedication of the Nether Seal team.

During the production process, we encountered numerous challenges. However, through collaborative teamwork, we overcame one obstacle after another. From the procurement of components to the optimization of assembly processes, every step embodied the team’s hard work and wisdom. All components used in these cert valves were sourced from high-quality domestic suppliers, such as Anhui Yingliu and Jiangsu Yingliu, ensuring the quality of the components but also laying a solid foundation for the localization process. Meanwhile, the full-time supervision and guidance provided by Dutch technical experts further guaranteed production quality.
