The Sharpe 40276 series inline stainless steel 316 globe valve has a screwed bonnet, non-rising stem, and socket weld 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 stainless steel 316 for higher strength and greater corrosion resistance than stainless steel 304. Stainless steel 316 is sometimes called "marine-grade stainless steel" due to its resistance to chloride corrosion. The maximum pressure is 200 pounds per square inch (gauge) (psig) for use with water, oil, and gas (WOG) at 350 degrees Fahrenheit. The valve has a screwed bonnet for tight assembly and reduced risk of leakage, and socket-weld ends for connecting to unthreaded pipe ends. The joined pieces are welded together to create a tight seal against leaks. This valve meets standards American Society for Testing and Materials ASTM A351 for quality assurance. 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.
