Floating four-way four-pad ball valves can provide three flow directions: L/T/X.  For applications with L and T flow directions, the following precautions:

       For floating four-way ball valve, if L flow or T flow is selected, it cannot be applied in the condition that the high pressure end is blocked, otherwise, the four-way ball valve may leak.
       When the four-way ball valve switches from position 1 to position 2, high-pressure end blockage occurs, leading to internal leakage of the medium in the high-pressure end pipeline during actual use.  This situation is determined by the structure of the floating four-way ball valve.  If customers must choose a four-way ball valve under such conditions, please communicate with us, and we will assist in selecting an alternative model.
