Matco-Norca has added two new forged carbon steel swing check valves — in threaded and socket welded — to its industrial grade valve product offerings. Swing check valves direct flow, prevent backflow and can be used in many applications.
These Class 800 check valves feature a stainless steel and graphite gasket and bolted bonnet. They are available in six sizes ranging in diameters from 11/2-inch up to 2-inch. The valves have a max pressure rating of 1975 PSI at 100 degrees Fahrenheit and a max temperature rating of 850 degrees Fahrenheit at 850 PSI. They conform to ASTM A105, ASME B16.34 and API 602 / API 598. To mitigate corrosion, these carbon steel swing check valves conform to NACE MRO175.
