RN brass ball valve is a type of valve that is commonly used in plumbing and industrial applications to regulate the flow of liquids or gases. It consists of a hollow brass ball with a hole in the center that is rotated by a handle or lever to control the flow of the fluid. When the handle or lever is turned, the ball rotates within the valve body to either block or allow the flow of the fluid through the valve. RN brass ball valves are typically made of high-quality brass, which makes them resistant to corrosion and other forms of wear and tear. They are often used in applications that require a durable, long-lasting valve that can withstand high pressure and temperatures. RN brass ball valves are available in a range of sizes and configurations to suit different applications, and they are widely used in a variety of industries, including oil and gas, chemical processing, and water treatment.
