The electric butterfly valve can be opened quickly in actual use, which is convenient and fast, has small fluid resistance inside the equipment, and is simple to operate and easy to start frequently. The electric butterfly valve can transport mud, and there is very little accumulation of liquid in the pipeline. Electric butterfly valve can achieve good sealing under low pressure. Such convenient use benefits from the simple wiring method of the electric butterfly valve.
Line type: 1, 2, 3 are 220V power input terminals, 1 is white line type, generally zero line, 2 is open control input, 3 is closed control input, blue line: electric valve closed power supply, red line: Electric valve open type power supply; 2 and 3 are connected to 220V live wire through a switch, and cannot be powered at the same time. It is better to use a changeover switch, which can only get electricity at a time). 5 and 6 are valve position feedback switches, (green wire: feedback common terminal signal): 5 is the signal feedback common terminal, generally (any one of feedback power is available), 4 is the valve is turned on when the valve is turned on, 5 is the valve Start signal; 6 is when the valve is turned on, 5 is turned on, and the valve start signal is given. In addition, this feedback type electric actuator has no power output, and 220V/DC24V power supply should be connected to the feedback loop. Black line: output signal power (220V) when the valve is open; yellow line: output signal power when the valve is closed.
