Swing check valves direct flow and prevent backflow, and can be used in many applications. These Class 800 check valves feature a stainless steel and graphite gasket and bolted bonnet, and are available in six sizes ranging in diameters from 1 1/2” up to 2”. The valves have a maximum pressure rating of 1,975 psi at 100° F and a max temperature rating of 850° F 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.
