Connector type:Flanged  |  Item Length String:12.50 Inches  |  Part Number:SV25314030 This class 300 Sharpe Valves 25314 series swing check valve is made of cast steel for higher strength and shock resistance. It has a bolted bonnet, welded seat, renewable seat ring, and flanged connections on both ends for bolting to compatible-sized pipe flanges. This valve can be installed to horizontal or vertical lines. This valve meets Northern Area Eastern Conference (NACE) MR0175 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.
