Description
A three piece ball valve is a type of valve that consists of 3 separate body parts, a main body and two connection ends. The connection ends are typically threaded / Flanged to the pipe allowing for the main body to be easily removed for cleaning and servicing with out the need to unthread the connection ends.
This makes the 3 piece valve ideal for applications that where regular cleaning or frequent maintenance is required where the internal components need to be cleaned or replaced without removing the entire valve from the pipeline.
Three piece valves are a type of two-way ball valve, since they allow for the fluid to flow in either direction straight through from the inlet to the outlet. They are often threaded / Flanged ball valves making them quick and easy to install.
3 piece stainless steel ball valves are widely used for a variety of sanitary applications such as food and beverage, pharmaceuticals, and chemical processing as well as in the oil and gas industries, wherever frequent maintenance and sanitation are required.
