About Sharpe Valves 25316 Series Stainless Steel 316

This class 300 Sharpe Valves 25316 series check valve is made 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. It has a bolted bonnet, integral seat, renewable seat ring, and flanged connections on both ends for bolting to compatible-sized pipe flanges. The maximum working pressure is 720 pounds per square inch (psi), and the working temperature range is -20 to 100 degrees Fahrenheit.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.
