4-Way Ball Valves
The 4‑way ball valve only needs to operate a wrench or actuator to rotate the ball 90 degrees, which can switch the flow direction of two media at the same time. It is both convenient and rapid, achieving the effect of one valve with multiple uses. The valve core and valve neck materials of the valve are austenitic stainless steel, and the valve seat material is PTFE, which can achieve good corrosion resistance and extend the service life of the valve.
