Pneumatic three-way ball valve is divided into L type and T type:
The L-type three-way ball valve is suitable for the switching of the medium flow direction, and can connect two channels perpendicular to each other;
The T-type three-way ball valve is suitable for the splitting, confluence or flow direction switching of the medium, and the T-shaped channel can make the three channels communicate with each other or Two of the channels are connected.
It is widely used in water supply, petrochemical, metallurgy, mining, textile, energy, paper, food, steel and other pipeline systems to switch the flow direction of the medium and to divert or mix the medium.
1: The fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2: Simple structure, small size and light weight.
3: Close and reliable, the sealing surface material of the ball valve is widely used in plastics, has good sealing performance, and has been used in vacuum systems.
4: Convenient operation, quick opening and closing, as long as the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5: The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally active, and it is convenient to disassemble and replace.
6: Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
