The G series mini solenoid valves are very popular in China and USA, most popular for controlling air, water, ink, coffee or something like this, not so dirty and easy to clean, one good example is the GU23-0.6-1.5LT and GU23-0.6-1.5L, good valves for coffee machine maker.

These mini valves are very smart, and we can easily change valves properties for different condition, it's not difficult to change 2/2 way valve to 3/2 way valve, normal close valve to normal open valve, and medium from air to water, and temperature from 60C to 150C……many options for coils, from 220VAC to 10VDC……E.MC has a good team to design all kinds of different mini valves with our experienced R&D department for valves. We make most parts by ourselves and easy to realize what customer wants.
