Non-Rising Stem Gate Valve

Product highlights and key procurement data

The double-sealing technology and modular design of our company's non-rising stem gate valves are highly popular in the market. The concealed stem gate valve adopts an innovative metal + soft material dual-sealing design. This design enables the valve to withstand a deep cold environment of -196℃ and also endure a high temperature test of 425℃. It can work stably in harsh environments such as chemical plants and power stations, truly achieving zero leakage.

In terms of quality, we are extremely meticulous. Every valve is subject to over 20 rigorous tests before leaving the factory to ensure full compliance with international standards such as API598 and GB/T13927. The actual measurement data shows that our leakage rate is always controlled within ≤0.01%, which is 5 times stricter than the industry standard. When randomly inspected by third-party testing institutions, our product qualification rate has remained at 100% for five consecutive years.The company has a powerful production system, with a monthly production capacity of over 100,000 units. It can not only meet the rapid delivery of large-volume orders, but also flexibly provide customized services for special diameters and different materials (such as ultra-low carbon stainless steel, Hastelloy alloy), covering all customer needs from standard products to non-standard parts.

These advantages make the gate valves produced by our company the preferred choice for purchasers when they are balancing quality, efficiency and cost.

Industry Application Case

The non-rising stem gate valve performs exceptionally well in practical applications. In the use of power plants, our valve can stably withstand high-temperature conditions of around 400℃. After being used in a certain power plant in Guangdong, feedback indicated that the maintenance frequency significantly decreased, and it remained in good condition after three years of use.

In the field of shipbuilding, our products have obtained the relevant anti-corrosion certifications. Some customers have reported that after being used on ocean-going vessels for five years, the valves still function normally and their corrosion resistance is indeed much better than that of ordinary products.

These actual cases demonstrate that our valves have indeed made efforts in material selection and manufacturing processes, and can meet the requirements of some special working conditions. Although the price is slightly higher, from the perspective of long-term use, the cost-effectiveness is still quite good.
