When the coil 2 electric valve core has 2, when the coil 2 lose electric valve core back to zero. When coil 1 have to electric valve core is down 1, when the coil 1 lose electric valve core back to zero. Three, there are three popular speak be gear 1/0/2. Double coil is in coil 1 have to report after the mechanical parts movement, after losing electricity position unchanged. This common is: 'three four-way valve' or 'three two-way valve'. This valve is very common. Coil 2 electricity, the location of the position of the mechanical parts from 1 to 2, maintain after losing electricity. Chongqing SANO the technology to do very well!
