Zhengmao Valve Wafer Lift Check Valve: A "Backflow Stopper" in Pipes, More Convenient with Floating Ball Valves
First, let's share some solid parameters with you: the valve body is made of gray cast iron, ductile 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 cold water, hot water, as well as neutral gases and liquids stably. The most crucial part is its sealing performance: the sealing surface is made of nitrile rubber or fluororubber, and the test pressure can reach 1.1 times the nominal pressure. As long as the medium flows in the correct direction, there will be no leakage. Unlike some check valves that "can't seal tightly" after long-term use, our valve comes with complete inspection reports and material certificates, making project acceptance a breeze.
Then let's talk about the advantages in use: it adopts wafer-type installation, which doesn't take up much space independently. It can be directly clamped between two flanges on the pipeline, and installation masters all say it saves time. The internal valve disc uses a lift-type design with a very fast response-once the medium stops, the valve disc immediately falls to seal, leaving no chance for backflow. A customer from a community water supply project once said that after installing this check valve, the water pump was no longer damaged by backflow, and the number of repairs was reduced by more than half. If the pipeline also needs flow control or emergency shut-off, it's perfect to match it with our floating ball valve: the check valve guards against backflow, while the floating ball valve is responsible for precise regulation or quick shut-off. The whole system is safe and efficient, and many customers have used this combination.
Now this check valve is widely used in scenarios such as municipal water supply, community heating, chemical fluid transportation, and power plant circulating water. For example, in chemical workshops, it can prevent cross-flow of different media; in community heating pipelines, it can avoid uneven temperature caused by hot water backflow. The most reassuring part is the after-sales service: this wafer lift check valve comes with a one-year warranty. Whether you need technical guidance during installation or encounter minor faults later, just make a call, and someone will respond within 24 hours. Spare parts are also shipped quickly, so normal pipeline operation won't be delayed.
Want to know more? Follow Zhengmao Valve's official website or WeChat official account. The latest product news and cases of customers using it well will be updated. For example, a chemical plant customer recently matched this check valve with the floating ball valve on the raw material transportation pipeline, greatly improving efficiency. 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.
