Results
Time to Breakaway is the time required to begin valve movement and is recorded when the
valve has moved ½% from the starting position.
Force at Breakaway is the force in the actuator measured at the breakaway point.
Time to Target is the actual time it took for the valve to arrive within 2% of the final value.
Result gives a pass/fail indication of the test based on the reference time to target and the
actual time to target.
