Products Details

The micro-retarding closed disc check valve is a specially designed valve that is mainly used to prevent the reverse flow of fluid, while effectively limiting the destructive water hammer to ensure the safe use of the pipeline. The valve is suitable for water, sewage, sea water and other media drainage pipe, with novel structure, small volume, light weight, small fluid resistance, reliable sealing, stable opening and closing, wear resistance, long service life and other advantages. Its working principle is to rely on the thrust of the imported medium to push the two valves smoothly, when the pressure of the imported medium drops lower than the outlet pressure, the medium will produce backflow, the valve disc automatically closes under the action of the spring and the media backflow, but the piston rod is in the extended position, the valve disc can not be completely closed, to achieve the effect of small slow closure.

In addition, the casting material of the micro-retarding closed disc check valve can be made of a variety of materials, such as ZG1Cr18Ni9Ti, ZC1Cr18Ni12Mo2Ti, CF8, CF8M, CF3, CF3M, etc., which is suitable for a variety of industrial fields, including chemical, oil, natural gas, machinery, medicine, paper, food and power generation.

The models of the micro-retarding closed disc check valve include HH46X, HDH48X and HH49X series, which are widely used in industrial and urban construction, and have received good feedback. The slow closing time of the valve does not exceed 60 seconds, which ensures that when the fluid stops flowing, the valve can be smoothly closed to avoid the occurrence of water hammer.

When installing and using the micro-retarded closed disc check valve, the following points need to be noted:

Do not make the check valve bear the weight of the line, and the large check valve should be supported independently.
The medium flow direction should be consistent with the direction indicated by the arrow on the valve body.
Select the appropriate installation method according to the valve type, the vertical flap check valve should be installed on the vertical pipe, and the horizontal flap check valve should be installed on the horizontal pipe.
The design concept of the micro-retarded closed disc check valve also includes ergonomic principles, taking into account the simplicity, accuracy and safety of user operation, as well as the long-term maintenance of product performance. For example, the cylinder is equipped with a transparent oil cup for quick and accurate understanding of the oil level, while the main operational considerations are displayed directly to the front-line operator through the signage, ensuring safe operation.

Overall, the micro retarded closed disc check valve is an efficient, energy efficient and easy to operate valve for a variety of fluid media and industrial applications.
