Overview and Application
The straight-stroke three-way converging/diverting control valve adopts a double valve core and valve seat guide structure to adjust and control the gathering and separation of media in several flow paths. Two flow paths enter and one flow path exits is called three-way converging. On the contrary, One flow path in and two flow paths out are called split flow. The standard combined/split flow path is designed as an unbalanced double-seat internal structure. At the same time, balanced internal parts can be used to effectively reduce the unbalanced force caused by medium pressure difference. The size of the throttling surface is changed to control the adjustment or cut-off function of the evenly divided flow composed of the confluence or divergence of any flow path. Special valve cage internals such as noise reduction and anti-cavitation can also be used according to the working conditions.
