A Class 150 check valve with a bolted cover is an automatic valve engineered to prevent backflow, capable of handling a maximum pressure of about 285 psig at ambient temperatures (approximately 100°F). Its pressure rating gradually decreases as the operating temperature rises. The bolted cover incorporates a gasket—typically a spiral-wound stainless steel design with graphite filler—to create a reliable, leak-tight seal between the valve body and the cover. This construction is standard for cast or forged steel check valves, making them widely employed in industrial applications such as oil, gas, and petrochemical processes.
