About Milwaukee Valve 572 Series Bronze Globe
This class 300 Milwaukee Valve 572 series inline bronze globe valve has a union bonnet, rising stem, bronze disc, and female National Pipe Taper (NPT) threads on both ends, and is used to control flow (throttling) in a pipeline or water plumbing system. The valve body and disc are constructed of American Society for Testing and Material (ASTM) B61 bronze for strength and corrosion resistance. This valve has maximum pressure ratings of 1000 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG) and 300 psig for steam working pressure (SWP). It has a union bonnet for simplified inspection of the valve interior, and female NPT threads on both ends for connecting to male threaded pipes. This class 300 valve meets standard Manufacturers Standardization Society (MSS) SP-80 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. This rising stem globe valve is for use in various pipeline or water plumbing systems. Globe valves control flow rates in a piping system by the lift of a vertical stem and disk, which must be turned to open and close the valve. A seated disc extends into the center of the valve to act as a plug to restrict or open the flow path, depending on how tightly the valve stem is turned. The stem on globe valves can be either rising (moves up as the valve opens) to indicate if the flow is on or off, or non-rising (stem height remains constant when the valve is either open or closed) for use in small spaces. Globe valves are used in various water, gas, air, and steam piping systems that require frequent throttling operations. The Milwaukee Valve Company manufactures manual and actuated valves, controls, and control accessories. The company, founded in 1901, and headquartered in New Berlin, WI, meets International Organization for Standardization (ISO) 9001:2008 and 14001:2004 standards.
