Electric three-way ball valves
Electric three-way ball valves are three-way switching regulating ball valves designed for diverting, splitting, or mixing flow media in three pipeline lines. They are typically available with flange or internal thread connections. The ball core can be designed in L-port or T-port configurations to meet different flow switching requirements, enabling various fluid control combinations in piping systems.
Features
1. Combines on-off shut-off and intelligent proportional regulation functions, allowing not only fluid isolation but also adjustment of pressure, flow rate, temperature, and other parameters.
2. Multi-functional for flow distribution and diversion, suitable for the proportional control and regulation of liquid, gas, steam, and other media.
3. Wide application range with multi-purpose functionality. Any port can serve as an inlet with zero leakage; three-way designs are available in both L-port and T-port structures.
4. Available as electric flange three-way ball valves and electric threaded three-way ball valves to suit different pipeline connection conditions.
Working Principle
Electric three-way ball valves can switch or shut off two mutually perpendicular passages, and close any one passage while connecting the other two, providing flexible control of media mixing or splitting. By selecting actuators with different functions, they can meet various operating conditions. These valves are widely used for two-position shut-off or proportional regulation in industrial systems including power, environmental protection, water supply, steam, and mechanical equipment.
