How many wires should be connected to the electric actuator of the French electric wafer soft seal butterfly valve? Analysis on the causes and solutions of internal leakage of electric control valve
、 The so-called electric on-off butterfly valve actually refers to the mutual combination of the electric actuator and the butterfly valve. Through ± 5 ° fine-tuning and the use of the internationally common SIO05211 connection standard platform, it can achieve the valve of precise matching. The electric on-off butterfly valve has been widely used in this era. The electric actuators mentioned here are classified into intelligent adjustment type, explosion-proof type and flameproof type in special environment according to the stroke torque control with rotation angles of 90 °, 120 °, 180 ° and 270 °. The power supply of the actuator is
