It is used to switch the flow direction or split or partial split.
The four-way ball valve is called a two-way water supply rotary valve (also known as an air reversing switching valve in a petrochemical system) in a power station system, and is suitable for the circulation system of liquid, gas, dust, slurry and solid particles. For example: the forward and reverse circulation water supply system of the power plant unit cooler. The traditional process piping method realizes the cooling forward and reverse circulation water supply. The device occupies a large space, high cost, and tedious operation (four valves need to be operated each time). When the water supply is wanted, valves 1 and 3 are opened and valves 2 and 4 are closed. During reverse water supply, valves 2 and 4 are opened, and valves 1 and 3 are closed. A four-way ball valve is used to replace the working principle of the manifold and valve group, which simplifies procedures, facilitates operation, reduces costs, facilitates control, and has good synchronization.
