Product Description

The Milwaukee Valve 515 series bronze swing check valve with female National Pipe Taper (NPT) threads on both ends is a class 150 valve used for restricting fluid flow to one direction. It has a hinged disc that swings onto the seat of the valve to block reverse flow. The valve body is made of American Society of Testing and Materials (ASTM) B-62 bronze for strength and corrosion resistance. This valve has maximum pressure ratings of 300 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG) and 150 psig for steam working pressure (SWP), and a cracking pressure of 0.5 psi. It has female NPT threads on both ends for connecting to male threaded pipes with tighter seals than straight threads. This class 150 check valve is for use in water lines, processing plants, and agricultural applications and meets standard MSS SP-80 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.

Check valves are used to restrict the flow of fluids and other loose materials through a pipe or passageway in one direction only. They have two ports – one for the fluid to enter the valve and one for the fluid to exit. They remain open when flow is moving in the correct direction and close when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. Ball cone valves utilize a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction. A swing check valve has a movable disc on a hinge, blocking reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate). Check valves are primarily used in water, gas, air, and steam lines.

The Milwaukee Valve Company manufactures manual and actuated valves, controls, and control accessories. The company, founded in 1901, and headquartered in New Berlin, WI, meets International Organization for Standardization (ISO) 9001:2008 and 14001:2004 standards.
