Check valve technical parameters details

Clamp check valve, also known as counter-flow valve, check valve, back pressure valve, check valve. This kind of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve.

Check valve for piping systems, its main role is to prevent media backflow, to prevent the pump and its drive motor reversal, as well as the container media release. Check valves are also used on lines where the pressure may rise to a level above the pressure of the main system auxiliary system. Check valve according to the different materials, can be applied to a variety of media on the pipeline. Check valve installed in the pipeline, that is to become the complete pipeline of the fluid components, the valve opening and closing process will be affected by the transient state of the system it is affected; in turn, the valve closing characteristics Occurrence of fluid flow on the state of action.

Clamp check valve for nominal pressure PN1.0MPa ~ 42.0MPa, Class150 ~ 2500; Nominal diameter DN12 ~ 1200mm, NPS1 / 2 ~ 48; Operating temperature -196 ~ 540 ℃ on the various pipelines, to prevent Media backwards. Through the selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea and other media.
