ABSTRACT:
A mechanical pressure gauge indicator for showing a position of a multi-turn non-rising water valve stem is disclosed. The mechanical pressure gauge indicator uses 180 degrees of turning motion to indicate various approximations of pressure downstream of the regulating valve. One half turn of the mechanical simulated pressure gauge indicator indicates ten turns of the multi-turn non-rising water valve stem.
