The three-way/four-way ball valve is used for switching, converging and diverging pipeline medium flow direction. It is widely applied in metallurgy, mine, petroleum, chemical industry, electric power, light industry, shipping industry and automation control systems, suitable for service conditions such as switching, mixing and diverging of fluid, gas and power.
The three-way/four-way ball valve is provided with reliable sealing and smooth flow channel so as to ensure accuracy of opening and closing through small fluid pressure loss and stable flow channel. According to the forms of flow channel, the valve can be classified into “Y” pattern three-way ball valve, “L” pattern three-way ball valve, “T” pattern three-way ball valve and “LL” pattern four-way ball valve.
“Y” pattern Three-way Ball Valve (q42 Type)
The form of flow channel is “Y” pattern, which can effectively realize switching from service condition 1 to service condition 2. It is mainly used for switching “Y” pattern pipeline flow direction.
“L” Pattern Three-way Ball Valve (q44 Floating Type,Q49 Trunnion Type)
The “L” pattern therr-way ball valve is used for switching pipeline medium flow direction. It can connect two flow channels that are vertical with each other. The ordinary “L” pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.
“T” Pattern Three-way Ball Valve (q45 Floating Type,Q48 Trunnion Type)
The “T” pattern three-way ball valve is used for switching, converging and diverging medium flow direction. The “T” pattern ball channel can make three channels connect with each other or two of them connect with each other to realize two, three of found kinds of functions. Different valve designs are adopted to realize different functions. Therefore, users shall make detailed descriptions to the service requirements when selecting and ordering the “T” pattern three-way ball valve, so that our company can make designs and configurations correctly. The ordinary “T” pattern floating three-way ball valve may not be suitable for some service conditions, which shall be paid special attention to when users select it.
“LL” Pattern Foru-way Ball Valve
The “LL” pattern four-way ball valve is provided with four seats to realize switching from service condition 1 to service condition 2. It can simultaneously switch the flow direction of two media, which realizes the effect of multiple functions in one valve with convenience and swiftness.
The work form is shown as follows:
1. When A(C) is the inlet, the two connections of A →B(C→D) or A→C(C→A) can be realized.
2. A cannot be realized.
3. A→D(C→B) or D→A(B→C) is impossible.
