Atkomatic Solenoid Valves

Circle Seal acquired the Atkomatic Valve Company in the late-1990s. For more than 75 years, Atkomatic has been serving the fluid controls industry, manufacturing heavy-duty industrial solenoid valves. Atkomatic solenoid valves handle the “open & close” control of gases, water, oil, steam and other clean media. Likewise, they can withstand the rigors of more demanding applications including cryogenic fluids, high pressure or super-heated steam, corrosive chemicals and more.
