There are T-type and L-Type 3way ball valve can make the three positive intersection pipeline contact to each other or cutting the third passage.Plays a role of shunting and the confluence.L-type 3-way ball valve can contact two positive intersection pipeline,But can't keep the third pipeline contact to each other ,only play a role of distribution.3-way ball valve in pipeline mainly be used to cutting ,distribution and change the media's flow direction.
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 transmisson shall be install in vertical
3-way ball valve's working principle is by revolving valve core to turn on or off the valve
L-type 3-way ball valve port,Adopt four plane seat ,balance force reliable sealing ,ball core with L port hole .Mainluy used for flow path reversing.
T-type port's 3-way four plane seat ball valve ,Adopt four plane seat force balance ,guarantee reliable sealing when latch channels,Mainly used for bypass flow ,mixed flow ,reversing and three way ports totally open.
1.Integration structure
2.3-way ball valve include T-type and L-type ,have long service life ,large flow capacity ,and small flow resistance.
3.Three -way ball valve according to different functions can be divided into two kinds of types as single and double function,single acting's feature is once the power supply in failure state, the power supply in failure state,the ball valve will be in a state of control system requirements.
4. Four surface valve seat type ,less flange connection ,high reliability ,realized the lightweight design.
Three-way ball valve is be used to cutting off,distribution and change the media's flow direction in the pipeline. Ball valve is the new type valve be widely used in recent years.It has the following advantages:
1.Low fluid resistance .It's resistance coefficient is the same as the same length pipeline.
2.Simple structure small volume,light weight
3.Tighterning and reliable,material of ball valve's sealing surface is PTFE,Sealed well ,strong corrosion resistance.
4..Easy operation ,Open or close quickly,from open or close as soon as rotate 90 degree easy control by long distance.
5. Easy to maintenance .simple structure ,sealing ring ordinary are active ,disassembling and replacement
is more convenient.
6.In full open ore full close,valve body and valve seat's sealing surface be insulate with media. Then medium through,does not cause the valve sealing surface erosion
