The 3-way ball valve has 3 straight flow path which through the valve does not become narrower on the inside. Three-way ball valve is suitable for switching, mixing and shunt of corrosive or non-corrosive medium like liquid, gas and powder. It can be divided into L-type three-way ball valve and T-type three-way ball valve. L-shaped three-way ball valve is used for switching flow direction while T-shaped three-way ball valve is used for medium shunt, confluence and flow direction switch. This 3-way design can connect three channels or two of them to each other. Three-way ball valve is generally double seat structure, four seat structure is optional, that depends on user requirements.
