Explosion-proof Electric Three Way Ball Valve
Driven by an explosionproof electric actuator, this three-way ball valve provides reliable flow diversion, mixing, and reversal with bubble-tight sealing — built for flammable and explosive service such as petrochemical processing.
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.
- T-port: four-seat design with balanced seating forces for dependable sealing; handles diversion, mixing, reversal, and full three-way flow.
- L-port: two-seat design for flow-path switching between two outlets.
