L-type q44f manual three-way ball valve has the advantages of compact structure, beautiful appearance and good sealing performance. L-type three-way ball valve is suitable for switching the flow direction of medium, and can connect the two vertical channels. (the following L-shaped flow chart)

1. Compact structure, quick opening and closing, smooth flow passage and small fluid resistance.
2. Good sealing performance: using PTFE elastic deformation of four sides seat material to realize no leakage sealing.
3、_ The valve has many functions: any port can be used as inlet without leakage, and tee can be made into L-type or T-type.
4. Convenient maintenance: after the system is depressurized, it is not necessary to remove the whole generation for inspection and maintenance.
5. 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 medium and to separate or mix the medium.
