A voltage, also called a potential difference or potential difference, is a measure of the amount of energy that is generated by the energy difference in the electrostatic field due to the potential difference. Its size is equal to the unit positive charge due to the electric field force from the A point to point B work done, the direction of the voltage specified from the high potential point to the direction of low potential. Voltage of the international unit system for the volts (V, referred to as volts), commonly used units are millivolt (mV), microvolts (μV), kV (kV) and so on. This concept is similar to the "water pressure" caused by the water level. It should be noted that the term "voltage" is generally used only in circuits where "potential difference" and "potential difference" are commonly applied to all electrical phenomena。

Solenoid valve has control coil, control coil voltage and DC, AC, and other well-known international brands Germany Ward WODE solenoid valve, for example, commonly used voltage DC 24V, 48V, AC 127V, 220V, 380V and so on.

But the world's voltage there are many kinds of standards are not the same, we distinguish between the introduction:

Voltage profiles of countries around 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, the Netherlands, Philippine, Thailand, Norway, Singapore, India, New Zealand, Australia

Note 1: 220 ~ 230V voltage in the country, also depending on the region and need to use 110 ~ 130V voltage and other circumstances, such as Sweden, Russia.

Most of the country's indoor electricity use 220 ~ 230V voltage, because the high pressure with power, high thermal efficiency and other advantages. Recently, Japan proposed a plan to raise the voltage, in the country caused widespread discussion.

The following are the voltage of each country:
