Solenoid valve voltage standards around the world

The international unit system of voltage is volts (V, referred to as volts). Commonly used units are millivolts (mV), microvolts (μV), kilovolts (kV), and so on.

　　 This concept is similar to the "water pressure" caused by high and low water levels. It should be pointed out that the term "voltage" is generally only used in circuits, while "potential difference" and "potential difference" are commonly used in all electrical phenomena.

　　 Solenoid valves have control coils. The working voltages of the control coils are DC and AC. Take the international famous brand WODE solenoid valve as an example. Commonly used voltages include DC 24V, 48V, etc., AC 127V, 220V, 380V, etc.

　　 But there are many kinds of voltages in countries all over the world, and the standards are different. Let’s differentiate and introduce:

　　 Voltage overview of countries in the world

　　100V: Japan, North Korea

　　110～130V: Taiwan, the United States, Canada, Panama, Cuba, Lebanon, Mexico

　　220～230V: UK, Germany, France, China, Singapore, Hong Kong (200V), Italy, Spain, Greece, Austria, Netherlands, Philippines, Thailand, Norway, Singapore, India, New Zealand, Australia

　　 Note 1: In countries where 220-230V voltage is used, 110-130V voltage is also used in combination according to regional needs, such as Sweden and Russia.

　　In most countries, indoor electricity uses a voltage of 220-230V, because high voltage has the advantages of power saving and high thermal efficiency. Recently, Japan has proposed a plan to increase the voltage, which has caused widespread discussion in the country.
