An 80NB Switch Valve Castings refers to a valve component with a nominal bore (NB) size of 80 millimeters, commonly used in piping systems to control the flow of fluids or gases. They are typically made from materials such as cast iron, ductile iron, carbon steel, stainless steel, or various alloys, depending on factors such as the fluid being handled, pressure, temperature, and corrosion resistance requirements. The switch valve casting is designed to withstand the pressure of the fluid or gas within the piping system. 80NB Switch Valve Castings are critical components in piping systems, providing reliable flow control and fluid handling capabilities in various industrial applications, including oil and gas, water treatment, chemical processing, and HVAC systems.
