Create a custom Pressure Safety Valve / Pressure Relief Valve Test to run on a FieldLab
Create a new valve test and add it to a FieldLab Pressure Calibrator to perform tests on pressure safety and pressure relief valves.
This feature requires:- FieldLab Desktop App version 1.24.0 or later installed on your PC. You can update from within the app if you already have it installed, or download the latest version for free.
- FieldLab Firmware version 1.123 or later installed on a FieldLab Pressure Calibrator. Learn how to update firmware.
1. In FieldLab Desktop, select "Test Modes"
2. Select the "New" button, and then select "PSV/PRV" from the dropdown menu.
3. Name the test mode
4. Select Crack & Reseat Detection
Auto Detection of Crack and ReseatWhen you select auto detection, the FieldLab will automatically detect, display, and save the crack & reseat pressures. Ideal for scenarios where the crack and reseat happen so quickly that it's difficult for a human to determine the exact crack pressure.
Manual Marking of Crack and ReseatWith this setting, the person performing the test watches the valve and manually marks the crack and reseat events with the press of a button on the FieldLab.It is recommended that you select the manual setting when testing liquid Pressure Safety Valves (PSV) or proportional relief valves (PRV).
5. Select the number of crack tests you want to perform on the PSV/PRV.
6. Select acceptable crack range
When you select Simple Crack Range or Conditional Crack Range you have the freedom to define your own custom parameters.When you select any of the following for acceptable crack range:
- ASME BPVC VIII.1 UG-134(d)(1)
- ASME BPVC VIII.1 UG-125(c)(3)
- ISO 4126-1
...specified standards will be applied to the test as defined by The American Society of Mechanical Engineers (ASME), or the International Organization for Standardization (ISO).
7. (Optional) Include a seat tightness test
If you are including a Seat Tightness Test, enter your desired settings for Length of test and Static Pressure Setting.When you include a Seat Tightness Test, the FieldLab will enable you to record in your test data that the Seat Tightness Test was performed, the pressure that was applied to the seal, the length of time the pressure was applied, and whether it passed or failed. The FieldLab Gauge interface will prompt you for PASS/FAIL status at the time of the test.
8. (Optional) Select Custom Data Fields to be included with the test data
For more information on creating and adding custom data fields, see Add Custom Data Fields to your Data Sets.
9. Save the new test mode
