Electric three-way ball valve adopts FOSD type, angular stroke electric actuator, which is powered by AC220V, AC 380V, or DC24V power supply voltage, and can be controlled by accepting (4-20mA5voC) current signal or voltage signal input from industrial automation instrument control system. Operation, to achieve proportional adjustment or two-position switching control of the process medium. The three-way ball valve is a new type of three-way switching control valve developed by integrating foreign advanced technology. The standard ball core has an L-shaped three-way double-port hole type. By changing the relative angle between the ball core and the pipeline, different fluids in the three pipelines can be realized. Combination control; T-shaped channel can be used for proportioning, suitable for proportioning adjustment and control of liquid, gas, steam and other media. Widely used in food, environmental protection, light industry, petroleum, papermaking, chemical industry, fire protection, air conditioning, water supply and drainage etc. in the automatic control system.
