These Class 800 check valves feature a stainless steel and graphite gasket and bolted bonnet, and are available in six sizes ranging from 1 1/2” up to 2”. The valves have a max pressure rating of 1,975 psi at 100° F and a max temperature rating of 850° at 850 psi. They conform to ASTM A105, ASME B16.34 and API 602/API 598.
