The DD-2 and DD-3 series compact designed direct-acting solenoid valve has stainless steel body and
offers superior corrosion resistance. Because it can be applied to various fluids, it is widely used for water
supply/drainage systems in a house, plant facilities and automatic controllers for industrial use, etc.
1.
Superior corrosion resistance with stainless-steel-made trim parts.
2.
Vertical or horizontal installation is possible.
