Each nominal size keeps this product’s fixed construction and has its own RFQ product code. Face-to-face standard and length are retained as part of the RFQ line. The remaining dimensions use the available reference data from the preliminary datasheet. All dimensions remain subject to quotation confirmation.
Review the available ASME lengths.
Available dimensional data provides one face-to-face length for each covered class, valve type and NPS. The source does not identify a governing face-to-face standard, so these values are not labelled ASME B16.10.
