l.
Establish the actuator output thrust requirements for operation under worst case conditions based on the MOVATS Incorporated differential pressure test data base.
2.
Determine actuator capability to provide the thrust requirement without exceeding its limits, including valve and actuator stress ratings and actuator reduced voltage stall thrust.
G R
The MOVATS Incorporated differential pressure (DP) test data base contains the results of MOVs that have been tested under DP conditions.
If sufficient data points for a particular type of valve are included in the data base, they can be used to predict thrust requirements for valves of that particular type, in lieu of performing DP testing to determine the thrust requirements.
This approach is included in the Union Electric Company (Callaway) response to IEB 85-03, which has been accepted by the NRC.
The Callaway response specified that if there are 4 or more data points from valves of the same type, manufacturer, orifice
- diameter, and stem diameter; or if there are 20 or more data points from valves of the same type; then further DP testing is not required for those categories of valves if 1) the data points are used themselves te calculate required thrust statistically or
- 2) the data points verify that a particular calculation method is conservative.
If a valve is adequately represented in the DP data base, the DP thrust requirement is calculated by MOVATS Incorporated as follows.
Linear regression is performed on the DP test data points to find the equation for the best-fit line through the data.
After a thrust value is predicted for the valve using the "best-fit" equation, a
90% confidence band, or tolerance is calculated and then added to the predicted thrust to obtain the
- thrust, b ve a, required by the valve to be able to operate against differential pressure, (DP Thrust Requirement).
Standard statistical analysis methods are applied for deriving the confidence interval.
Attachment 1 explains the methods in more detail.

0 Page 4 of 12 To obtain the minimum target thrust, which i,s the value used to set the torque switch during MOVATS valve diagnostic testing, the "DP Thrust Requirement is multiplied by a factor that accounts for torque switch repeatability and accuracy of the MOVATS diagnostic system instruments.
All calculations provided are based on the MOVATS DP data base as of the date on which the calculations were performed.
Because the calculations are performed using actual data from the data base, the calculation results can change as data is added to the data
- base, All data used in the calculation is available for review at MOVATS Incorporated in Marietta, Georgia.
If a valve is not adequately represented in the DP test data base, then the valve should be tested under pressure to determine the actual thrust required or to verify that a particular calculation method is conservative for the valve type.
Testing may be performed at several reduced pressure points and the required thrust calculated by extrapolating the test data to the maximum pressure.
The procedure for calculating the confidence band for the extrapolated thrust values is the same procedure used to calculate thrust using data points from the DP data base.
The magnitude of the confidence band is influenced by the number and values of test data points as follows:
1.
The greater the difference between the actual test pressures and the maximum expected pressure, the lower the confidence.
2.
The greater the number of tests performed at different pressures, the higher the confidence.
Testing at a minimum of two different pressures is required in order to calculate a confidence band for the extrapolated thrust values.
3.
The greater the scatter of data points, the lower the confidence.
If the valve can only be tested at one pressure point, consider the following:
1.
The test results may be compared to the calculated thrust requirement for the reduced pressure.
If the calculated value proves to be conservative, the calculational method can be used with relative confidence when computing thrust required at full differential pressure.
2.
Theoretically, a thrust value obtained by extrapolating from a single data point is more reliable than a value obtained MOVATS Incorporated Technical Resources
pi
E.R. 1.0, Rev.
0 Page 5 of 12 for a generic thrust equation alone, because the extrapolated value is based on empirical data from the specific valve in its actual condition, rather than on values fudged to be applicable to all similar valves.
Note, that a statistically valid confidence band. cannot be computed without at least two test points (in addition to the zero point); therefore, engineering Judgement must be used when using the one point extrapolation approach.
3.
The one data point will add a value to the industry data
- base, and combined with the rest of the data, may allow for validation of a generic calculational method for that particular type.
In conclusion, if a valve cannot be tested under its maximum differential pressure conditions, the next best option is to test the valve at a minimum of two different pressures.
If data can only be obtained at one pressure value, this data point may be used to verify the manufacturer's thrust calculation method or added to the industry data base for future reference.
V V
The general criteria that the valve must meet in order to be considered operable under worst case conditions are as follows, 1) the minimum available thrust must be greater than the DP thrust requirement; and 2) the maximum available thrust plus stem running load must be less than both the reduced stall thrust capability and the component stress limits.
A.

Capability Evaluation Before Testing A "pre-test evaluation" of the capability of a valve to perform its design function is provided as part of the MOVATS Incorporated thrust calculations.
This evaluation consists of comparing the maximum allowable running thrust (MART) to the estimated stem running load.
For this pre-test evaluation, the stem running load is estimated as follows:
1000¹ for stem diameter up to 1500¹ for stem diameter up to 2500¹ for stem diameter up to 4000¹ for stem diameter up to 5000¹ for stem diameter above 1
inclusive 1.5" inclusive 2.5" inclusive 4" inclusive 4o The maximum allowable running thrust (MART) is calculated as follows:
MART Thrust Limit - Highest Target Thrust
- where, Thrust Limit (lesser of valve/actuator commercial rating and reduced voltage stall thrust)
Highest Target Thrust (greater of opening or closing Target thrust)

E.R. 1.0, Rev.
0 Page 7 of 12 If the estimated stem running load is greater than MART, and if the valve is set up to deliver the required thrust, either the component stress limits or the stall thrust limit must be exceeded.
If this is the case, the following options should be considered and planned before the test.
1.
Component Stress Limitation Exceeded If the target thrust plus estimated stem running load is greater than the actuator or valve stress limits, ~
v a stress analysis can be performed to determine the effects of the higher thrust levels on long-term operability of the motor operated valve.
In general, valves and actuators operating within normal stress limits may be operated many times without excessive wear and damage.
When applied thrust levels are increased beyond documented thrust limits, a valve or actuator may still perform without damage, but accelerated wear and fatigue of critical components can occur If the valve is not stroked frequently and/or the required thrust values are not significantly higher than the documented allowable limits of the valve or
- actuator, a stress analysis is likely to show that the useful life of a MOV is not significantly shortened by the higher thrust conditions.
In this case, performing a stress analysis "may )ustify an increased thrust rating, allowing the valve to be set to deliver the required thrust, and thus provide operability documentation.
2.
Stall Thrust Limitation Exceeded If the target thrust plus estimated stem running load exceeds the actuator's calculated reduced voltage stall thrust value, a stall thrust test can be conducted.
Since the standard stall thrust calculation is generally conservative, a stall thrust test is likely to prove that the actual 100% voltage stall thrust (and thus the reduced voltage stall thrust) is higher than the calculated value.
Please note that care should be taken prior to performing this test to ensure that actuator or stem limits are not exceeded without having a plan in place for verifying operability afterwards.

C.
Capability Verification During/hfter Testing The pre-test evaluation determines if the valve is capable of operating against maximum conditions ~ the valve is set, up properly.
During or after the testing, the actual operating characteristics of the valve should be evaluated in three steps to determine if the valve actually ~ set up properly to deliver its design requirements.
1.
Compare Actual Running Load to MART MART can be used as a quick and conservative indicator f wh ther the valve can operate under worst case DP oad conditions. If both the open and close motor loa running loads are less than HART, the valve ~ capable of operating under design DP conditions without operating outside the limitations of the valve/actuator.
Th ext steps are to check the actual thrust output e n a d 3 against requirements and limits {see steps 2 an below).
If the motor load running load is greater than MART, this indicates that sufficient available thrust to meet the calculated DP requirements cannot be obtained without exceeding the capability or stress limits of the actuator.
At this point the following options should be considered:
a.
Sin'ce the motor load running load {which includes internal actuator running load) is a conservative measure of the actual stem running load, a more in accurate measurement could reduce the stem runn ng load below MART.
This can be achieved by removing the stem nut and obtaining open and close motor load signatures.
The differences between the motor load running loads with and without the stem nut installed represent the open and close stem running loads.
b.
Since a calculated value is inherently conservative, a
DP test to determine the valve's actual DP thrust requirement may reduce the requirement to within the valve limits.

Increase MART by performing a stall test to determine actual capability of the actuator if stall thrust is the limiting factor, or d.
Increase MART by performing a stress analysis to increase stress limits of valve/actuator, 2.
Compare Thrust Settings to Thrust Requirements If the motor load running load is less than MART, the next step is to verify that the valve is set-up to deliver the required thrust by comparing the minimum available thrust to the DP thrust requirement.
If the minimum available thrust is less than the DP thrust requirement, the torque switch setting should be increased,
~hoyle ensuring that the valve capability and stress limits are not exceeded, (see Step 3).
3.
Compare Thrust Settings to Thrust Limits If the valve is set-up to deliver the required thrust, the final step is to ensure that the valve limits are not exceeded by verifying the following:
Maximum Available Thrust + Stem Running Load (estimated or measured) must be less than:
Reduced Voltage Stall Thrust and Valve/Actuator Rating and:
b.
Maximum Available Thrust + Inertia + Stem Running Load (estimated or measured) must be less than 1.1 x Actuator Limit If the limits are exceeded, the torque svitch setting should be reduced, while ensuring that the minimum available thrust is sufficient to meet the DP thrust requirement.
If this is not possible refer back to the options listed in Step l.

The following assumptions are made when using the thrust calculation methodology described above.
1.
Stem friction due to packing drag is assumed to be equal for both pressurized and non-pressurized conditions.
2.
It is assumed that the valve is in good working order;
- however, MOVATS+ thrust calculations are based on a differential press~re test data base that includes valves of differing ages and conditions.
3.
No foreign internal obstruction to valve travel is assumed.
4.
The coefficient of friction that dictates the operator's torque to thrust conversion (stem factor) is assumed to remain constant over time.
5.
Unless provided on customer data sheet, the calculated yield values of valve components are assumed to be greater than the operator's commercial rating.
6.
Thermal transients are assumed not to affect the thrust required to open valves of all types.
7.
In cases where the closing line pressure was not recorded, the closing line pressure was assumed to be equal to the closing differential pressure.

Page 1 of 3 CALCULATING CONFIDENCE BANDS
Reference:
1.
Business Statistics, 3rd Edition, 1983, by Wayne Daniel and James C. Terrell, (Chapter 9).
Assumptions:
1.
The thrust required to open and close a gate or globe valve is a linear function of differential pressure across the valve.
2.
For every differential pressure (x), there is a subpopulation of thrust values (y) for identical valves.
The thrust values are normally distributed about some mean value.
3.
The standard deviation of thrust values is the same for all subpopulations and is unknown.
4.
The mean values lie on some stx'aight line.
(i.e., There is a linear relationship between diffex'ential pressure and the average thrust values.)
Procedure:
Perform a regression (least squares) analysis of the measured DP thrust (thrust above running load) vs differential pressure for at lease 4 identical valves.
The (0,0) point can be used along with this measured data.
The result is an equation of the form:
y a + bx where y thrust required x
