The Visual indicator is a mechanical device that graphically displays the angular displacement of a quarter turn valve or and other device operating between 0 and 90 degrees.
The Indicator represents a true indication of valve position.
It is infinitely adjustable, and delivers a 100% change of indication, displaying 90 degrees of rotation by utilizing an amplified mechanical drive.
The valve position transmitters have enclosures meeting the following
