2/2-way Solenoid Valve with 
servo diaphragm, G 3/8 - G 2
Servo-assisted solenoid valve with servo- 
diaphragm for the control of liquid or gaseous 
Medium. A pressure difference of 0.5 bar is required for a complete switchover. The modular
coil system allows the interchange of the coils 
over all ori? ces to be in line with the nominal 
power and circuit function.
