What is a check valve?

Check valve, also known as check valve or check valve, refers to the valve that automatically opens and closes the valve flap by means of the flow of the medium itself, and is used to prevent the back flow of the medium, also known as check valve, check valve, counter flow valve and back pressure valve. .

Check valve function:

The purpose of the check valve is to prevent backflow of media in the line. The bottom valve of the water pump suction is also a check valve. The valve of the opening and closing member is opened or closed by the flow of the medium and the force to prevent the back flow of the medium from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only the media to flow in one direction to prevent accidents.

The check valve is installed in the piping system and its main function is to prevent backflow of the medium. The check valve is an automatic valve that is opened and closed by the pressure of the medium. The clamp type check valve is suitable for the nominal pressure PN1.0MPa~42.0MPa, Class150~25000; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540°C for various pipelines, used to prevent The media is reversed. By using different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
