This checklist helps valve buyers prepare the test article, valve type and end connection, nominal size, required test medium, pressure range, shell or seat-leakage test, clamping orientation, utilities, instrumentation, reporting and safety requirements before a valve test-bench review. It is a project-input guide, not a published AMY CNC test-bench model or a statement of verified pressure capability.
What decision does this valve test bench checklist support?
Use the page to define the testing problem before asking for equipment selection or quotation. A test bench must be reviewed against the actual valve, test method, pressure envelope, end connection, handling method, available utilities, measurement method and required record. A model name should not be selected from nominal diameter alone.
| Project input | What the buyer should provide | Why it matters |
|---|---|---|
| Valve identity | Valve type, drawing or tag, body material, trim if relevant, mass and operating orientation. | Defines the test article and handling condition. |
| End connection | Flanged, threaded, socket-weld, butt-weld, wafer or another end form; include dimensions and rating data. | Controls adapters, sealing and clamping interfaces. |
| Size range | Minimum and maximum nominal size plus actual envelope dimensions for unusual bodies. | Controls fixture travel, loading space and changeover scope. |
| Test scope | Shell or body test, seat leakage test, back-seat test, set-pressure test, vacuum test or another defined procedure. | Separates the required sequence and measurement task. |
| Test medium | Water, air, nitrogen or another buyer-specified medium, including cleanliness and recovery requirements. | Changes pressure generation, piping, venting and safety controls. |
| Pressure data | Required pressure for each test stage, hold time, ramp method and pressure unit; provide the governing buyer specification. | Prevents a single maximum-pressure value from being applied to every valve size or test. |
| Clamping and loading | Horizontal, vertical or tilting preference; lifting method, allowable external load and any restriction on end loading. | Controls orientation, handling and protection of the test article. |
| Leakage assessment | Visual, bubble, flow-rate, pressure-decay or another defined method, with unit and acceptance rule. | Determines sensors, collection method and record format. |
| Utilities | Electrical supply, compressed-air pressure and flow, water supply and drainage, floor space and ambient conditions. | Defines what can be operated at the installation site. |
| Control and records | Manual, semi-automatic or automatic sequence; gauge class, calibration needs, test identification, report fields and data export. | Defines operation, traceability and buyer acceptance records. |
| Safety and documents | Guarding, exclusion zone, pressure release, operator language, manuals and buyer-required standards or procedures. | These items require explicit review and cannot be inferred from a generic machine image. |
Which files should a buyer prepare?
- Valve drawings, end-connection dimensions and clear photos of representative test articles.
- A test schedule listing test type, medium, pressure, hold time and acceptance method for each valve size.
- Expected daily or shift volume, changeover pattern and loading method.
- Available utility data and the intended installation layout.
- Required report sample, language, calibration record and document list.
- Any buyer-controlled test procedure, safety rule or standard that must be reviewed.
How should the test sequence be described?
- Identify the test article and connection method.
- State how the valve is loaded, sealed and clamped without assuming an allowed clamping force.
- List filling, venting, pressure ramp, hold, leakage observation and depressurization steps.
- Define the measurement unit, acceptance rule and required test record.
- Separate mandatory buyer requirements from optional automation, reporting and handling features.
Can this page confirm an AMY CNC test bench model or pressure rating?
No. AMY CNC does not currently publish a named valve test-bench model, verified working range, pressure capability, test standard or certification on this page. Those facts require accountable product data and a project-specific review. Competitor dimensions, pressures and features used during research are not AMY CNC specifications.
What should be confirmed before quotation?
Confirm the responsible equipment source, model designation, permitted valve range, test media, pressure by valve size and test stage, sealing and clamping method, instruments, control sequence, report format, safety controls, installation scope, documentation and acceptance procedure in writing.
Where does the project review continue?
- Return to the Valve Machine Selection Matrix when the equipment route is still unclear.
- Review current machine and requirement-review categories without treating a held category as a published product family.
- Submit a secure valve test bench inquiry with the actual valve and test data.
