Feature

RVQ641F screwed pneumatic three-way ball valve includes split flow and convergent flow type and it is a multi-port ball valve with two-side or four-side valve seat. Any port can be used as inlet without leakage. Three ways can be made into L-shaped port or T-shaped port and operate through inputting 4~20 mADC signal and 0.4~0.7 Mpa gas source.The product is widely applied to foodstuff industry,environmental protection industry,water treatment industry,light industry,petreochemical industry,paper-marking industry,etc.
