H44Y、H44HThe type pn16-pn25 swing flange steel check valve is applicable to the pipeline of petroleum, chemical, pharmaceutical, chemical fertilizer, electric power industry and other working conditions with pressure of 1.6-25mpa and working temperature of - 29 - + 550 ℃. The applicable medium is water, oil, steam and acid medium to prevent the backflow of medium, To prevent the pump and its drive motor reversing, as well as the discharge of media in the container.

H44Y、H44HType B swing flange steel check valve pn16-pn25 is automatically opened and closed by the force generated by the flow of medium in the pipeline, which belongs to an automatic valve. The check valve is used in the pipeline system, its main function is to prevent the reverse flow of medium, prevent the pump and its driving motor from reversing, and discharge the medium in the container. The check valve can also be used to supply the auxiliary system in which the pressure may rise above the main system pressure.

 

 

Check valve installation should pay attention to the following matters
1. In the pipeline, do not make the check valve bear the weight, large check valve should be independently supported, so that it is not affected by the pressure produced by the pipeline system.
2. During installation, the direction of medium flow should be consistent with the arrow direction of valve body.
3. Lift type vertical disc check valve shall be installed in vertical pipeline.
4. Lift type horizontal disc check valve shall be installed on horizontal pipeline.
