ELECTRICAL CHARACTERISTICS Coil insulation class F Connection Screw terminals Standard voltages DC 

(=) 24V AC (~) 24V - 115V - 230V/50Hz AC (~) 24V - 120V - 240V/60Hz

Solenoid valves satisfy all relevant EC directives

Solenoid valve Manual Reset function which means that the valve has to be energized as well as manually operated 

before it stays in the “l(fā)atched” position. The No Voltage Release function will make sure that the valve trips if de-energized
