How to adjust the switching degree of Dalian electric speed regulating butterfly valve actuator? 4. The electric butterfly valve needs to adjust the flow in use and is controlled by a pneumatic actuator.
、 4、 Q944F, Q945F electric flange three-way ball valves: Q944F, Q945F electric flange three-way ball valves use AC220V single-phase AC as the power source, bear the 220V switch signal from the control system (or operator), and drive the reversible single-phase gear reducer through single-phase power switching, so that the ball valve can complete the reversing effect on the pipeline fluid according to the assembly requirements of the rules. Product name Electric flange three-way ball valve Product model Q944F/Q945F Product diameter DN15-DN250 Product pressure 1.0MPa-6.4MPa Product raw material Carbon steel, stainless steel Seven commonly used electric ball valves
