Top-entry Ball Valve

Let's lay out the parameters clearly for everyone, no tricks involved: the nominal diameter ranges from DN25 to DN300, so it's suitable for both precise control of small and medium-sized pipelines and medium transmission in large-diameter pipelines; the nominal pressure can withstand 1.6-10MPa, making it suitable for medium-high pressure working conditions in oil transmission and pipelines for corrosive media in chemical workshops; it has a wide applicable temperature range, working stably between -40℃ and 200℃, and is compatible with common media such as water, crude oil, and acid-alkali solutions-no need to switch valves back and forth.

Its core highlight is the "top-mounted" design-during maintenance, there's no need to remove the entire valve from the pipeline. Just open the top bonnet, and you can directly replace the valve core and seals. Even if the pipeline is still connected to the medium (after shutting it off in advance), there's no need to move the pipeline, saving much more effort than side-mounted valves. If you choose the model with the floating ball valve structure, the ball can float slightly with the medium pressure, making the sealing surface fit tighter. The leakage rate is as low as Class VI of GB/T 13927, so there's basically no need to worry about liquid or gas leakage-it's safe and material-saving.

In practical use, it's extremely versatile: in oil gathering and transportation pipelines for oil extraction, it's high-pressure resistant and wear-resistant, and won't easily break even with long-term use; in the feed pipes of reaction kettles in chemical parks, it's corrosion-resistant and accurate in controlling flow, eliminating the need for frequent shutdowns for maintenance; even in municipal sewage treatment pipelines, the valve body is made of 316 stainless steel, which is resistant to sewage corrosion and easy to maintain. Compared with ordinary ball valves, it not only has a longer service life but also reduces material waste during pipeline disassembly and assembly, making it easier for workers to operate and saving a lot of operation and maintenance costs in the long run.
