Features:
Size 50mm to 300mm
Flange ANSI 300
Body Carbon Steel (WCB)
Seat Metal
Pressure 50 Bar @ ambient
Carbon Steel Swing Check Valve. 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 meet standards API 594, API6D, BS1868 & ASME B16.34, RF Flanges according to ASME B16.5, face to face according to ASME B16.10, testing and inspection according to API598.
