Q14F & Q15F Three-Way Low Pressure Ball Valves

The Q14F and Q15F three-way ball valves are manually operated internal threaded soft-seated three-way ball valves with PTFE seat sealing. By rotating the ball 90° to change the medium flow direction, they achieve pipeline flow switching, diversion and merging control.
Q14F (L-Port): The ball has an L-shaped flow passage. It only connects two perpendicular ports while the third port remains fully closed. It is used for medium flow direction switching and cannot realize three-way interconnection, diversion or merging.
Q15F (T-Port): The ball has a T-shaped flow passage. Any two ports can be connected, and all three ports can be interconnected simultaneously. It supports medium diversion, merging, mixing and multi-path switching.
