A three-way ball valve is a multiport valve with three openings to which the pipes are connected. These ports are described as one inlet and two outlets, or one outlet and two inlets depending on the required application. These ports in the ball help the fluids, gases, and slurries mix and divert from

1. INTRODUCTION
The main reason for using 3-way ball valves for industrial purposes is that 3-way ball valves can mix and divert two different fluids, which helps in changing physical and chemical properties.
In this research paper, the reader will get to know the methodology followed, the technology used, designing, fabrication, and experimentation that will enable to obtain the characteristics curve of a three-way ball of varying sizes. It is a composition of various elements of the start-to-end procedure implemented, which are key factors to successfully obtain the desired results. The setup was made to obtain the characteristics curve and is a contribution to academia and industry in the fields of fluid mechanics, mechanical engineering, and control engineering.
1.2 Type of Flows and Material Composition There are mainly two patterns in which the fluid in a 3-way ball valve can be made to flow. L-type 3-way ball valve: It is also known as a diverter valve, as the flow takes place from one inlet port which is fixed, as the output of flow takes place from either of two outlet ports located at 90° from the inlet on both the left and right sides. So, in L-type flow, the inlet side is fixed, but the output direction depends on the position of the lever. The outward flow of water can be altered by adjusting the lever.
1.1 What is Valve, Ball Valve, and Three-Way Ball Valve The word valve is derived from the Latin word ‘Valva’, which means a moving part of a door. A valve is a device used for controlling the passage of fluid along the length of a tube, pipe, or duct by the action of opening and closing the passage.
T-Type: It is a type of flow that is similar to the L-type, but here the flow takes place in either type.
A three-way ball valve is a type of valve that starts or stops and regulates the flow of fluid by using a hollow, perforated ball that is mounted inside the main body. The regulation is done by the movement of the ball which is done with the help of a lever connected to it.

Completely shut off the flow. Flow coming from one inlet can be split into two different outlets. The flow can be made to continuously flow in one direction while blocking the outlet.
