ANSI SWING CHECK VALVE

ANSI Swing Check Valve Descriptions

ANSI swing check valve is also called one-way valve or non-return valve, which is used to prevent of mediums back flow in the pipeline. The disc of the check valve is action depending on the mediums itself flow pressure, so the check valve is belonging to automatic valve types. Because the swing check valve is only allowed the mediums to flow in one direction, we should note the arrowhead on the check valve when mount it in horizontal position. Swing check valves are widely used in series of industries, especially in oil & gas filed, power plant, etc. We can manufacture the ANSI swing check valve in accordance with ASME b16.34 and BS 1868.
