Abstract
By incorporating driver switching circuitry and a suppression network as parts fixed with respect to a valve housing rather than remotely from the valve housing, advantages including transient suppression at the housing are obtained rendering the valve better suited for low power machine control operation. Both AC and DC operated valves with driver switching circuits and suppression networks are disclosed.
