The Sharpe 45314 series inline carbon steel globe valve has a bolted bonnet, non-rising stem, and flanged connections on both ends, and is used to control flow (throttling) in a pipeline or water plumbing system. The valve body is constructed of American Society for Testing and Material (ASTM) A216 carbon steel for tensile strength and hardness. The maximum working pressure is 285 pounds per square inch (psi). The valve has a bolted bonnet for tight assembly and reduced risk of leakage, and flanged end connections for bolting to compatible pipe flanges. The stem/wedge connection meets the API 600 Pull test. This valve meets the following specifications for quality assurance: American National Standards Institute (ANSI) B16.34, B16.10, B16.5, B16.25; and American Petroleum Institute (API) 598.
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.
Sharpe Valves manufactures a wide variety of valves, including stainless and carbon steel ball, gate, globe, and check valves. The company, founded in 1986 and headquartered in Chicago, IL, meets International Organization for Standardization (ISO) 9001:2008 standards based on Sharpe's design and manufacturing of valves.
