Abstract
The coil of a solenoid-operated valve is fluid-isolated from fluid whose flow is controlled by the valve by providing the solenoid with an imperforate transverse end wall having a radially inner annular ferromagnetic zone forming one portion of the stator, a radially outer annular ferromagnetic zone forming another portion of the stator, and a radially intermediate annular zone of non-magnetic material separating the radially inner and radially outer ferromagnetic zones.
