FAQ
Does this product fully comply with the API 623 standard?
The entire product line strictly adheres to the API 623 specification—from wall thickness design and material selection to the inspection process—and is also compatible with relevant ASME standards. We can provide the corresponding compliance documentation.
What are the advantages of the angle and Y-type configurations compared to conventional straight-through models?
The angle configuration can directly replace elbows to change the direction of the medium flow, reducing potential leak points in the pipeline; the Y-type configuration features a diagonal flow path design, resulting in lower flow resistance, making it more suitable for applications requiring high flow rates while also needing regulation capabilities.
Can these valves meet the low-leakage requirements of ISO 15848?
The entire product line supports customization for ISO 15848 certification. The optional bellows seal design easily achieves the highest leakage class, strictly controlling media leakage rates to meet VOC emission control requirements.
What are the key differences between API 623 globe valves and standard industrial globe valves?
These are heavy-duty products with pressure margin redundancy, structural rigidity, and material grades far exceeding those of standard models. They are specifically designed for high-risk, heavy-duty operating conditions such as oil refining and power plants, offering superior long-term operational reliability.
What are the additional advantages of globe valves equipped with bellows?
Metal bellows completely isolate the valve stem from the medium, thoroughly eliminating the leakage pathways associated with traditional packing. There is no need for frequent packing re-tightening, and there is no risk of medium leakage during long-term operation, making them suitable for high-risk medium applications.
