Abstract
A valve system having a valve position indicator is disclosed. The valve position indicator allows for viewing of the valve position from one or more viewing locations. In one example, the valve position indicator includes a side valve open/close indicator and a top valve open/close indicator on a valve assembly. An indicator locking mechanism securely locks the valve position indicator in alignment with a position of a control valve.
