An eccentric motion
The eccentric plug rotates by lifting away from the sealing surface, clearing the flow path on opening and returning to contact upon closure. This distinct geometry sets it apart from a standard ball valve.
Body, Seat, and Elastomer
Standard construction features a ductile iron body, an elastomer-encapsulated wedge, and a corrosion-resistant seat face. Verify NBR or EPDM compatibility based on the process fluid and operating temperature.
Verify correct flow direction and mounting orientation prior to installation
In English, this product line corresponds to eccentric plug valves. For slurry or solids-handling applications, the flow direction, shaft orientation, and plug position must be confirmed with the manufacturer.

| Selection Point | Documented Information |
|---|---|
| Size and Pressure Ratings | Standard DN80 to DN1600, PN10 to PN16 as per the detailed brochure. Custom configurations available upon manufacturer engineering review. |
| Body and Closure Member | GGG50 ductile iron with epoxy coating. Vulcanized NBR-lined plug. EPDM available as an option. |
| Sealing Solutions | The standard configuration provides reliable sealing in the flow direction specified by AVM. Do not assume bi-directional shut-off. |
| Actuation | Lever-operated on smaller diameters, with gear, electric, pneumatic, or hydraulic actuation available depending on the configuration. |
| End Connections | EN1092-2 flanges or custom bolt patterns engineered to project specifications. Verify dimensions, thickness, and allowable pressure ratings. |
| Normative Reference | AWWA C517 standard verified by AVM declaration dated June 1, 2026. Compliance documentation for the proposed configuration is required. |
ANSI Class 125 or 150 drilling compatibility alone does not determine the valve's pressure rating. The approved submittal data sheet and drawing remain the definitive references.

The AVM brochure specifies standard unidirectional shut-off. Any backpressure requirements must be communicated prior to final valve selection; the standard configuration should not be treated as a bidirectional valve.
Select throttling applications may be accommodated following technical verification. Flow rate, differential pressure, open position, and erosion risks must be provided.
Diameter, face-to-face dimensions, flange specifications, flow direction, overall footprint, and operating conditions. A photo of the nameplate and a piping isometric drawing help our specialists ensure seamless interchangeability.
