Zhengmao Valve Wafer Dual-Disc Check Valve: A "Backflow Guard" in Pipes, More Worry-Free with Floating Ball Valves
First, let's share some solid parameters with you: the valve body is made of cast iron or 304 stainless steel, which can be selected according to the transported medium. The nominal diameter ranges from DN40 to DN300, capable of withstanding a pressure of 1.0MPa to 2.5MPa, and the applicable temperature range is -10℃ to 120℃. It can handle tap water, sewage, as well as neutral fluids in petroleum and chemical industries. The most crucial part is its sealing performance-the sealing surface is made of nitrile rubber or fluororubber, and the leakage is almost zero when closed. Unlike some check valves that "drip and leak" after long-term use, our valve comes with complete test reports and material certificates, which can be taken out directly during project acceptance, saving a lot of trouble.
Then let's talk about the advantages in use: it adopts wafer-type installation, which saves more space than flange-type check valves. Masters don't need to struggle with lifting heavy parts, and two people can finish the installation in half an hour. The dual-disc structure has a very fast response-once the medium stops, the valve discs close immediately, without valve seat wear caused by large backflush force. Moreover, the flow resistance is very small, and the pressure loss when the medium passes through is 20% lower than that of ordinary check valves. The pump doesn't need extra effort, which can save a lot of electricity. If it is matched with our floating ball valve in the transmission pipeline-such as the raw material pipeline in a chemical workshop-the floating ball valve is responsible for precise flow regulation, and the check valve prevents medium backflow. The whole set is efficient and safe, and many customers have adopted this configuration.
Now this valve is used in municipal water supply, sewage treatment plants, oil transmission pipelines, and circulating water pipelines in chemical plants. For example, in the water supply pipeline of a residential area, it will not suck in air after peak water consumption; in the sewage discharge pipeline of a sewage treatment plant, sewage will not flow back to pollute the sedimentation tank. The most reassuring part is the after-sales service: this wafer dual-disc check valve comes with a one-year warranty. Whether you need technical guidance during installation or encounter minor problems later, just make a call, and someone will respond within 24 hours. Spare parts are also shipped quickly, so the pipeline will not be out of service for too long.

For example, a sewage treatment plant recently matched this check valve with the floating ball valve on the aeration tank pipeline, achieving excellent results. These practical experiences will be shared with everyone. If you have technical questions or want a quotation, feel free to contact us. We will definitely not beat around the bush and explain things clearly to you.
