The "LL" type four way ball valve only needs to operate the wrench or the actuator to turn the ball 90 degrees, and simultaneously the flow direction of the two media is switched, which is convenient and rapid, and the effect of a valve is realized. The four way reversing valve, a water supply valve to achieve positive and negative switching, each turn 90, a water supply switch, used four valves, water supply valve 1, valve 2, 4 open, closed 3; reverse water supply valve 2, valve 1, 3 open, 4 closed, a four valve replacement now, the operation is convenient.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.

One or two valve seat sealing three - way ball valve has a compact structure, beautiful appearance, good sealing performance. Can also realize the switching of the pipeline intermediary flow. Can also make the resistance of the two channels perpendicular to the connection or close.
Two, the four seat sealing ball valve three beautiful shape, compact and reasonable structure, which not only enables media flow switch, also can make the three channels connected with each other, but also to turn off any channel to another channel connectivity, control of media in the pipeline or shunt flexible confluence.
