At the same time, the butterfly valve controls the current flowing through it accordingly, and uses the principle of increasing the current passing area to better control the current passing through. In this process, the resistance is relatively small, so the energy saving effect is achieved. Thus, this small current plays a corresponding role in ensuring the personal safety of users. In order to consolidate the safety protection, butterfly valves are more equipped with electrostatic devices and important structures to prevent fire. With its good design concept, butterfly valves can better avoid the hidden dangers in use, which can ensure the safety problems in use.

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
