Can be applied in food,beverage,brewing,dairy,pharmaceutical and chemical industries,with an intended purpose of controlling the flow of fluids with viscous or particulate matters.
There are two types of three way ball valve ---T-shaped and L-shaped ball valve.
For T-shaped type,the three channels can be mutually connected while simultaneously shutting off the third channel,thus playing the role of diversion and confluence.
For L-shaped type,only two of the channels can be connected but the third channel cannot be connected simultaneously,thus playing the role of distribution.
Three-way ball valve and plug valve can be classified into onesame type.
Their difference is that the closing part of three-way ball valve is a sphere, and the sphere rotates around the axisto open and close the valve.
Three-way ball valve is mainly used to cut off,distribute and change the flow direction of media and there is norisk of detained liquids getting mixed with new liquids.
Working Principle:
3-way ball valve's working principle is by revolving valve core to turn on or off the valve
Matters need attention by installation or maintenance 3-way ball valve:
1.Need reserve place of rotary valve handle
2.Cannot be used as a throttle
3.Ball valve with transmission shall be install in vertical
