Safe solenoid valves for harsh environments

The new ATEX certified 221g series stainless steel Parker Hannifin solenoid valves are proposed as an economic solution to the food, pharmaceutical, oil and gas markets, but, more generally, in applications where there are corrosive liquids, chemicals and gases (ie potentially explosive atmospheres).

Thanks to the high strength 316L stainless steel  and the FKM fluoroelastomer fluid and chemical agent resistant seals, the 221g series combines the long life with reduced maintenance. Given the flow capacity of up to 170 liters/min, the new valves enable the size of customer installations to be reduced, resulting in cost reduction of approximately 10%.
At the basis of the new series, forty years of experience and technology already used in the brass valves of the same family. Thanks to the modular design, the 221g valves are assembled by choosing from different windings including ATEX, IP67, UL/VDE compliant ones. For this reason they are also used in systems that use detergents (in addition to the food industry, they are also used car washes or industrial washing machines). The series is available in 2-way version, normally closed with capacity from 3/8 inch up to 1 inch..
