The internal disc allows flow to pass forward, which opens the valve. The disc begins closing the valve as forward flow decreases or is reversed, depending on the design. The function or purpose of a check valve is to prevent reverse flow. Construction is normally simple with only a few components such as the body, seat, disc, and cover. Depending on design, there may be other items such as a stem, hinge pin, disc arm, spring, ball, elastomers, and bearings.●Swing checks are a simple design using a disc attached to an arm that is hinged at the top of the valve (at the 12 o’clock position). Reverse flow and gravity assist the valve in closing. Swing checks can be used for most media and generally provide good flow capacity. They range in size from 1/2 inch and smaller to 50 inches and larger, and are available with threaded, socket weld, flanged, or butt weld end connections. Swing checks are typically easy to inspect and maintain. In most cases, repairs can be performed with the valve in the line. Because of their design, swing checks are not fast-closing valves due to the travel distance from full open to close.●Piston, or lift, check valves are available as inclined (Y pattern) or conventional (90 degree) body designs. In either case, a body-guided disc moves within the body bore. The body guide ensures alignment of the seat and disc when the valve closes. Piston check valves are available from 1/4 inch to 24 inches and larger. Smaller valves, 1/4 inch to 2 inches, are normally provided with a spring to assist in closing and to ensure the disc slides back to the seat when installed in vertical lines. The body design selected will determine the pressure drop; inclined designs will provide the best flow performance. Piston check valves are available with threaded or socket weld ends for 2 inches and smaller. Larger valves are available with flanged or butt weld ends. Special end connections are available, but you should consult the valve manufacturer. Piston check valves can normally be inspected and repaired in line. Exercise caution when these valves are used for dirty media because that media could cause the disc to stick inside the body bore.Specifications: Product Name Cast Steel Swing Type Flange ends Check Valve DIN Standard PN16~PN641.
