Check valve is one flow direction valve, which ensures flow in one direction and prevents backflow. It is also known as a non-return valve and it can be used in a vertical or horizontal pipeline. ​The material used in the high-pressure check valve is commonly Carbon steel or stainless steel and it depends on the workability and needs in an industrial setting.

It is also available in different sizes such as DN8 to DN50, usually referred to as 1/4” to 2”. ​The standard working pressure of the high-pressure check valve is 420 bars for size 1/4” to 1”, while pressure reduces to 315 bars from size 1 1/4” to 2” when valve sizes get bigger.
