Non-rising Stem Cast Steel Gate Valve

Let's clarify the parameters clearly without tricks: the nominal diameter ranges from DN50 to DN400, suitable for both main water supply pipelines in residential areas and industrial pipelines in factories; the nominal pressure can withstand 1.6-10MPa, capable of stably shutting off common fluids such as tap water, sewage, oil, and chemical media; the applicable temperature range is -20℃ to 200℃, basically covering the transmission of daily hot and cold media. Moreover, the valve body is made of cast steel or stainless steel, which is corrosion-resistant and wear-resistant-even when transporting slightly corrosive media, it's not a problem.

Its core highlight is the "non-rising stem" design: the valve stem is hidden inside the valve body, unlike rising stem valves where the stem is exposed and takes up space. It can be easily installed in narrow basement pipelines or workshops with dense equipment. Additionally, the valve stem does not directly contact the medium, so it's not easy to rust or get stuck, and it switches smoothly-workers don't need to exert much effort during daily operations. If you've used our floating ball valve before, you know Zhengmao never compromises on sealing. The sealing surface of this non-rising stem gate valve is made of cemented carbide, with sealing performance far exceeding that of ordinary gate valves. The leakage rate can reach Class VI of GB/T 13927, so there's basically no need to worry about liquid leakage.

It also has a wide range of practical applications: in the water supply and drainage systems of residential areas or office buildings, it can stably control water volume; in the raw material transmission pipelines of chemical plants, the corrosion-resistant material ensures safety; in the pipelines of sewage treatment plants, it has strong anti-fouling ability, reducing clogging troubles; even in the heating pipelines of thermal power companies, it can work normally under high-temperature conditions. Compared with ordinary gate valves, it not only saves space and is easy to maintain but also extremely durable-no need to replace parts frequently, which can save a lot of operation and maintenance costs in the long run.

We also stand firm on after-sales service with a one-year warranty. Whether you need technical guidance during installation or encounter minor malfunctions during use, you can contact our after-sales team at any time-someone will respond 24 hours a day, so you won't have to delay production or daily life due to valve issues.
