Evidence scope

The retained official product route documents: Flowserve's Flow Control Division designs, manufactures and distributes engineered-to-order and configured-to-order isolation valves, control valves, valve automation products and related services. This dossier uses that cited route as the editorial scope. [S13]

The retained research coverage separates company identity from the named product evidence. It does not turn one model or series into a claim about unlisted company-wide operations. [S27]

Procurement fit

The Argus FK76M ball valve is classified by the manufacturer for industrial use in oil and gas, petrochemicals, chemicals, power and water service. The Flite-Flow product line is described by the manufacturer as Y-pattern globe-valve technology intended for nuclear service. The Durco G4, G4Z and G4R Marathon Sleeveline range is positioned as a non-lubricated plug valve family. Final configuration, standards, availability and lead time should be confirmed directly with Flowserve for each project.

Technical capabilities

Documented technical attributes for the Argus FK76M include trunnion-mounted ball valve construction in stainless steel, with a supply length of 4.6m. The Durco G4, G4Z and G4R Marathon Sleeveline family is documented as non-lubricated plug valve construction, also with a supply length of 4.6m. The Flite-Flow line is documented as Y-pattern globe-valve technology for nuclear applications. Detailed pressure class, temperature limits, sleeve materials, actuation options and standards compliance are not publicly documented and must be confirmed with the manufacturer.

Markets and applications

Documented application sectors include oil and gas, petrochemicals, chemicals, power and water for the Argus FK76M trunnion-mounted ball valves. The Flite-Flow Y-pattern globe-valve technology is documented for nuclear service. The Durco G4, G4Z and G4R Marathon Sleeveline non-lubricated plug valves are referenced within the same industrial categories; specific media compatibility and service envelopes are not publicly documented. Project-specific suitability must be confirmed with Flowserve.

Evidence limitations

Headquarters location (Irving, Texas) and country (United States) are documented. Corporate size, employee count, annual capacity and revenue are not publicly documented. Detailed standards compliance listings, third-party certifications and quality management accreditations are not publicly documented.

Recent financial-news signals are excluded from the specification record.

Editorial summary

Flowserve Corporation, headquartered in Irving, Texas, United States, is recorded in this directory under two product categories: flowserve and plug valve. The flowserve entry covers Argus FK76M trunnion-mounted ball valves. The plug valve entry covers Durco G4, G4Z and G4R Marathon Sleeveline non-lubricated plug valves. Both categories share a documented supply length of 4.6m. Specifications beyond those listed should be confirmed directly with the manufacturer before procurement decisions.

Frequently asked questions

What Plug Valve product is documented for Flowserve Corporation?

The retained product material names Argus FK76M trunnion-mounted ball valves. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S5]

Which common buying fields are not published in the retained sources?

The retained source packet does not publish Certifications, Availability or stock. Those fields are intentionally left out of the procurement snapshot rather than inferred from a related series, a product image or the company identity. [S27][S34]

Research notes

The retained first-party packet supports a richer product-level reading surface, but it does not yet contain 600 words of distinct cited content. This noindex dossier remains in reviewing status until additional source-backed facts are retained.
