About Sharpe Valves 20276 Series Stainless Steel 316

The Sharpe Valves 20276 series swing check valve is made of stainless steel 316 for strength and greater ease in welding than stainless steel 304. The lower carbon content of the material minimizes harmful carbide precipitation due to welding, ensuring corrosion resistance. It has a stainless steel 316 disc, screwed cap, and female National Pipe Taper (NPT) connections on both ends. Female NPT threads connect to male threaded pipes, creating a tighter seal than straight threads. The maximum pressure is 200 pounds per square inch (gauge) (psig) for use with water, oil, and gas (WOG) at 350 degrees Fahrenheit. This valve meets American Society for Testing and Materials (ASTM) A351 standards for quality assurance.Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.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.
