Procurement snapshot

Only hard product-level facts retained from the cited source route are shown below. A missing buying field is handled separately, rather than estimated from the listed series.

Published construction
The cited DS-31 route specifies brass C3771B and screw connections. [S4]
Published envelope
The DS-31 route states 1 MPa maximum pressure and -20 to 80 °C operating temperature. [S5]
DS-31; Manual Angle Type Needle Valves
Official product image [S6]

Evidence scope

The retained official product route documents: Fujikin documents DS-31 as a manual angle-type needle-valve series. This dossier uses that cited route as the editorial scope. [S6]

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. [S8]

Procurement fit

Specify the Fujikin DS-31 when the application requires a manual angle-type needle valve with brass C3771B body construction and screw connections, and the operating envelope remains within the published 1 MPa maximum pressure and -20 to 80 °C temperature range. The cited route does not document alternative body materials, end connections, or pressure classes, so confirm medium compatibility and final configuration directly with the manufacturer.

Technical capabilities

The Fujikin DS-31 manual angle-type needle valve is documented with brass C3771B body construction and screw-type end connections. Published operating limits are 1 MPa maximum pressure and a temperature range of -20 to 80 °C. No further dimensional data, flow coefficients, seat materials, or actuation options are publicly documented within the cited route. Engineers should request detailed specifications from Fujikin for parameters outside this envelope.

Markets and applications

Fujikin's documented scope is limited to the needle valve category, with the Fujikin DS-31 series as the cited manual angle-type offering. Specific end-use industries, application sectors, or typical service media are not publicly documented in the available material. The published pressure and temperature envelope suggests general low-pressure fluid handling duty, but final application suitability must be confirmed directly with the manufacturer.

Evidence limitations

Company founding year, employee count, manufacturing footprint beyond Osaka, and revenue figures are not publicly documented. No customer references, quality certifications, or compliance marks are listed in the cited material. Detailed dimensions, flow coefficients, seat and stem materials, leak rates, testing standards, and lead times for the Fujikin DS-31 are not publicly documented. Alternative series, sizes, pressure classes, and end connection variants within the needle valve category are not publicly documented.

Editorial summary

Fujikin Incorporated is a Japan-based manufacturer headquartered in Osaka. Within the needle valve category, the company's publicly documented offering is limited to the Fujikin DS-31 series of manual angle-type needle valves. No additional product lines, complementary fittings, divisions, or business segments are publicly documented in the cited material. Procurement and engineering reviewers should treat the DS-31 as the only verified needle valve entry from this manufacturer.

Frequently asked questions

What Needle Valve product is documented for Fujikin Incorporated?

The retained product material names Fujikin DS-31 manual angle-type needle valves. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S6]

Which published construction should a buyer compare?

The cited product material records: The cited DS-31 route specifies brass C3771B and screw connections. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S4]

Which published envelope should a buyer compare?

The cited product material records: The DS-31 route states 1 MPa maximum pressure and -20 to 80 °C operating temperature. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S5]

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

The retained source packet does not publish Annual sales, 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. [S8]

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.
