Actuator capability (degraded) Stroke time


BWROG DC Motor Methodology Update 2020

In December 2020 the BWR Owners Group (BWROG) revised the Excel spread sheet used for calculating DC MOV stroke time and motor capability. The primary changes in the revision are as follows. 1. Expanded the capability to calculate the Functional Actuator Capability

(FAC) for user defined load profiles. 2. For globe valves, added the capability to input a user defined Cv profile

in lieu of using the default linear profile. 3. Revised the spread sheet logic to exactly match the stepwise procedure

in MPR-2093 Rev. 3 by: a) Removing pre-stroke iterations on gearbox efficiency for valve opening stroke

applications which do not wedge/unwedge (i.e., globe valves, butterfly valves, or gate valves with X% set equal to 0%).

b) Adjusting the size of the stroke increments during the portion of a gate valve stroke between 0% and –X%.

4. Corrected the Darcy equation for calculating globe valve loss coefficient (flow resistance).

5. Added the fluid density correction factor used in equation for calculation of estimated flow rate.

6. Corrected the equation for calculation of Available Motor Torque at Unwedging and the Maximum Allowable Thrust at Unwedging.

BWROG DC Motor Methodology Update in MIDAS

In addition to items 1 through 3 above, TVA requested additional functionality in the Midas DCMM. These items are summarized as follows: Incorporation of the TVA custom closed thrust profile for ADDD gate valves. The TVA

custom thrust profile is based on the EPRI Performance Prediction Methodology (PPM) calculated thrust parameters; required thrust to achieve flow cutoff and the required thrust to achieve hard seat contact. The thrust profile in the BWROG spread sheet is based on either the required thrust to achieve flow cutoff or the required thrust to achieve hard seat contact.

Incorporate the TVA custom open thrust profile for ADDD gate valves. For ADDD gate valves the default thrust profile is developed per MPR 2093 Rev 3 Table 2-1, “Load Profile Coefficients”. Based on Table 2-1 the maximum opening thrust occurs after unwedging in the 4% to 7% stem position. For TVA Midas the open FAC will be selected based on the stem position associated with the maximum Load Profile Coefficient in lieu of the thrust at the 0% position.

Incorporation of TVA custom open and close FAC thrust profile for wedge gate valves and globe valves. When a “User Input” thrust profile is selected the new Midas function provides the option to use the packing and piston loads derived from the “User Input” source (i.e. PPM calculation or DP test) in lieu of the BWROG methodology of calculating the piston load and using the bounding design packing load.

Incorporation of a logic function that allows the End-User to select which DCMM torque output to use for margin calculations. For the closed direction either the torque at TST, close FAC, or the minimum of the 2 can be selected. For the open direction either the torque at unwedging, open FAC, or the minimum of the 2 can be selected.

3. Revised the spread sheet logic to exactly match the stepwise procedure in MPR-2093 by removing pre-stroke iterations on gearbox efficiency for valve opening stroke applications which do not wedge/unwedge (i.e., globe valves, butterfly valves, or gate valves with X% set equal to 0%). MIDAS already had this option and will retain it for backwards compatibility. Users can change selection.

QUG 2021



Incorporate the TVA custom open thrust profile for ADDD gate valves. Select the FAC value at 0% instead of the max value over the profile. This matches the behavior of the MPR spreadsheet for Use Default

QUG 2021



NOTE: for Input Stem Thrust, MIDAS will select FAC as the largest value over the profile, matching the behavior of the MPR spreadsheet
