Today, a DN1200-sized tilting check valve with weight hammer in the Jinbin workshop has completed the entire production process and is undergoing the final packaging operation, about to be sent to the customer. The successful completion of this water check valve not only demonstrates the exquisite manufacturing techniques of the workshop, but also highlights the significant value of large-sized micro-resistance slow-closing check valves in the field of industrial fluid control.

Large-sized check valves, with their unique design, possess several notable features. Firstly, strong flow capacity is its core advantage. The DN1200 flanged check valve can meet the demand for large-flow fluid transportation, with small pressure loss during the transportation process, which can effectively improve the operational efficiency of the system. Secondly, it features high structural stability. Made of high-strength alloy materials, the valve body has a uniform wall thickness and can withstand harsh working conditions such as high pressure and high temperature. Its service life far exceeds that of butterfly check valve. In addition, large-sized check valves have excellent sealing performance. Through the precise processing of the sealing surface and the valve core, they can minimize the backflow of the medium to the greatest extent and ensure the safe operation of the system.

As a high-end category among large-sized cast iron flap valve, the micro-resistance slow-closing check valve has irreplaceable applications in multiple key fields. In urban water supply projects, it is widely installed on the main water transmission pipes of water plants. It can not only meet the large water supply demand during peak hours but also prevent water hammer through its slow-closing function, protecting the pipelines and pump equipment. In the circulating water system of thermal power plants, this non return valve can precisely control the direction of cooling water delivery, prevent backflow of water during shutdown, and ensure the safe shutdown of the generating units. In large-scale sewage treatment plants, the corrosion-resistant design can adapt to the complex composition of sewage media. Meanwhile, the slow-closing function can reduce pipeline vibration and lower equipment maintenance costs.
