Normally open servo assisted solenoid valves

Empire Controls range of direct acting solenoid valves are suitable for water, air and oil at temperatures of -10 deg C to +90deg C. The servo assisted solenoid valve has a far higher pressure rating as it uses the differential pressure across the solenoid valve to help it to close with the solenoid operator. There must be a difference of 0.1 bar from the up stream and down stream pressures across the solenoid valve. 3/8" 0.1-20 bar pressure rated solenoid valve 1/2" 0.1-20 bar pressure rated solenoid valve 3/4" 0.1-20 bar pressure rated solenoid valve 1" 0.1-20 bar pressure rated solenoid valve 1 1/4" 0.1-10 bar pressure rated solenoid valve 1 1/2" 0.1-10 bar pressure rated solenoid valve 2" 0.1-10 bar pressure rated solenoid valve
