Four-way ball valve, also known as four-way circulating valve, is mostly used in the forward and backward circulating water supply system of power plant unit cooler.The traditional process pipe distribution method can realize cooling and reverse circulation water supply, which occupies large space, high cost and frequent operation.The four-way circulating valve is adopted to replace the working principle of manifold and valve set, which simplifies the procedure, facilitates the operation, reduces the cost, facilitates the control, and has good synchronicity.It has been successfully applied to the national "west-to-east power transmission" backbone projects: xiluodu of the three gorges group, xiangjiaba hydropower station, etc.
