Non-slam check valves

APPLICATION

Check valves are devices designed to prevent the return flow of the working fluid.
They are installed in pipe systems to prevent leakage and loss of working fluid and to protect devices from damage that would produce backflow of fluid. These are self-acting devices, which perform their function automatically, without a drive system. They alowe the fluid to flow in one direction, otherwise their shut-off body automatically closes the bright opening of the pipe and thus prevents undesired backflow of fluid.
Closing is done with the help of a spring and the pressure force of the return fluid.
Check valves can be mounted in horizontal and vertical position, and since they allow the flow of working fluid only in one direction, it is necessary to pay attention during installation that the direction of the arrow on the valve housing corresponds to the direction of movement of working fluid in a given pipeline.
They are used in plants for obtaining, preparing and distributing water, in communal facilities, in irrigation systems, in various plants of the chemical and petrochemical industry and in energy plants.
