Carbon Steel Swing Check Valve with silver primer coating. Allows for a large flow rate and little head loss/pressure drop across the valve due to the full bore design and recess for the disc to sit in when fully open. Designed to BS 1868, flanges according to ASME/ANSI B16.5, face to face according to ASME B16.10, testing and inspection according to API598. Ideally suited for liquid fuels, diesel and oils.
