SWING CHECK VALVE THREADED ENDS

Swing Check Valve Threaded Ends Type Descriptions

Swing check valve threaded ends type 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 threaded ends type is widely used in series of industries, such as water supply, water treatment and chemical industries, etc. We can manufacture the swing check valve threaded ends type in accordance with ASME b16.34 with sizes of 1/2″ to 2″.
