Features
Three-way ball valves manage flow diversion and confluence. Available as multi-port valves with either two (L-port) or four (T-port) seats, any port can serve as the inlet with bubble-tight shutoff.
L-port: two-seat design for flow-path switching between two outlets.
T-port: four-seat design with balanced seating forces for dependable sealing; handles diversion, mixing, reversal, and full three-way flow.
