Pneumatic 4 way floating ball valve  introduction
Pneumatic 4 way floating ball valve is the X type vertical channels ball valve,four channel distribution from all sides, when ball core rotation 90 degrees,Pneumatic 4 way floating ball valve can make the two channels to achieve mutually close,This series of Pneumatic 4 way floating ball valve mainly supply in the power station system two-way water supply rotation valve. Each rotation 90 degree, can be switch water supply mode. Pneumatic 4 way floating ball valve can instead of four valves, simplify the procedures, Simple operation, lower cost, easy to control, good synchronization.
