Factors Influencing the Purchase of VOG Iran Wafer Butterfly Valve

The purchase of a VOG Iran wafer butterfly valve depends on several technical, quality-related, and economic factors that must be evaluated beforehand. One key factor is the system’s nominal pressure, as these valves are typically manufactured in PN10 and PN16 classes and must match the pipeline pressure. The body material, usually ductile iron GGG40, and disc materials such as stainless steel 304 or 316 should be selected based on fluid type, corrosiveness, and operating temperature. The sealing material NBR, EPDM, or Viton also has a major impact on valve durability and performance. Pipe size, installation space, and compatibility with different flange types are additional important criteria. The final price is influenced by valve weight, epoxy coating quality, branding, and availability of spare parts. Evaluating these factors ensures a cost-effective and reliable selection.
