Ball Valve Series
Description
The L-type three-way shut-off ball valve adopts a two-piece ball valve structure, while the T-type three-way shut-off ball valve adopts a one-piece structure. It is mainly used for shut-off, distributing, and changing the flow direction of the medium in pipelines.
Share:
High pressure resistance with excellent sealing performance.
Low flow resistance loss in the chamber, compact and attractive appearance.
Suitable for pipelines conveying liquids and gases.
Three-way ball valves are available in L-port and T-port designs, mainly used for the flow control and shut-off of gas / oil in pipelines. They feature cast or forged valve bodies, with inserted downstream seats and carburized hardened valve stems. Depending on material selection, the valves can meet the requirements of unidirectional or bidirectional sealing.
