# AzTexnoQaz — 3D visualization notes

This is a public review of a visual prototype, not an engineering digital twin or a maintenance procedure. All shown internal reconstructions are conceptual. Dimensions, materials, clearances and operating behavior are not verified. No pressure readings or gas-flow simulation are depicted.

## Reference basis

- ESKA ERG-H1: [manufacturer page](https://en.eskavalve.com/products/direct-acting/erg-h1/). Rev.0 manual dated 02.01.2024, pages 12–14, sections A–A/B–B and parts list informed the simplified model. The translating half-casting is a conceptual cutaway, not a real disassembly method.
- PLUM MacBAT 5: [manufacturer page](https://gas.plum.pl/en/product/macbat-5-2/). Manual edition 25, October 2024, page 50 figure 7.1 informed broad component arrangement. Boards, batteries, hinge details and materials are simplified.
- Honeywell/Elster EK280: [operating instructions](https://docuthek.kromschroeder.com/download.php?doc=68063&lang=en), issue 2024-01 (j), figures 7–8 and 29–30. Reconstructed enclosure and interior are conceptual; cover motion is illustrative.
- ESKA EGV: [manufacturer page](https://en.eskavalve.com/products/gas-valves/egv/). Exterior family study only; exact variant is unconfirmed.
- BROEN BALLOMAX: exterior derived from manufacturer STEP 8600416065 010, BBM60461 DN65 PN16. [Official CAD listing](https://www.broen.com/documentation/cad-step-files/broen-ballomax/l-handle/full-bore/flange/pn-16/flange-x-flange/). No internal assembly is shown. Rendered finish is an appearance study. This reference belongs to a district-heating/industrial catalog; gas-service suitability is not claimed.
- NATEK AG family: [manufacturer page](https://natekenerji.com/ag-konut-tipi-diyaframli-gaz-sayaci/). Exterior-only study; exact correspondence between the AG4 reference and seller AG4TC record is unresolved.
