Abstract
A gas valve actuator for a gas valve. The gas valve actuator includes a non-conductive support bobbin and an insulated copper wire wound about the support bobbin to form a coil. A magnetic flux concentration member extends through the non-conductive support bobbin. To actuate the gas valve actuator, a current is passed through the coil, which produces a magnetic field that actuates an armature to move a valve seal away from a valve seat of the gas valve. Because the gas valve actuator may be exposed to a gas stream, the coil may be coated with an anti-corrosion coating through a spray or brush process, a potting process, through a dipping process, or in any other suitable manner.
