A small size three-piece ball valve is a type of valve used to control the flow of liquids or gases in a pipeline. It is called a “three-piece” valve because it consists of three main parts: two end caps and a central body. These parts are typically bolted together, which allows for easy disassembly, maintenance, and cleaning without having to remove the entire valve from the pipeline.Small size three-piece ball valves are designed to be compact, making them suitable for applications where space is limited.The three-piece design allows for easy access to the internal components, making maintenance and cleaning straightforward.Small size three-piece ball valve is a versatile and reliable option for controlling fluid flow in various industrial applications, such as Chemical Processing, Food and Beverage, Pharmaceuticals, Water Treatment, Oil and Gas.
