An ASTM A351 CN7M Globe Valve is a type of valve manufactured from an austenitic stainless steel grade known as CN7M Alloy 20. This material is frequently used as an equivalent to Monel 400 grade in valve production. CN7M Alloy 20 consists of a minimum of 19% chromium along with cobalt, carbon, copper, manganese, molybdenum, 32% nickel phosphorus, sulfur, silicon, and tantalum in its composition. The globe valve, which differs from a ball valve, is employed for regulating the flow of fluid in a pipeline. It features a movable plug or disc element and a stationary ring seat contained within a generally spherical body.
