POSITION INDICATOR REFERENCE CHART
On an ORBIT Actuator or an ORBIT Valve with a rising stem valve position
indicator, the indicator rod shows valve position. To determine if a valve, or
valve and actuator package is achieving full travel, measure the protruding
portion of the indicator rod in the closed position. Cycle the valve and measure
the indicator rod in the open position. Subtract to find valve travel.
