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 material choices
The cited NV/SV route lists stainless steel, brass, Alloy 400 and A105 options in inline or angle patterns. [S4]
Published envelope
The NV/SV page lists 6,000 psig / 413 bar at 100 °F maximum operating pressure and -65 to 600 °F operating temperature. [S5]
NV & SV Series
Official product image [S17]

Evidence scope

The retained official product route documents: Hy-Lok documents NV and SV as needle-valve series in inline and angle patterns. This dossier uses that cited route as the editorial scope. [S8]

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. [S10]

Needle Valve

Documented series: Hy-Lok NV and SV Series needle valves.

Hy-Lok documents NV and SV as needle-valve series in inline and angle patterns. [S8]

Documented specifications for Needle Valve
Pressure rating69bar [S11]
Published material choices
The cited NV/SV route lists stainless steel, brass, Alloy 400 and A105 options in inline or angle patterns. [S4]
Published envelope
The NV/SV page lists 6,000 psig / 413 bar at 100 °F maximum operating pressure and -65 to 600 °F operating temperature. [S5]
  • Hy-Lok NV and SV Series needle valves. [S6]

Selection fit: Start with NV or SV when the cited pattern, material options and published operating envelope fit the duty. Confirm medium, pressure, temperature, end connection and final configuration with Hy-Lok. [S9]

Plug Valve

Documented series: Hy-Lok P Series in-line plug valves.

Hy-Lok documents the P Series as an in-line plug-valve range with stated throttling capability. [S12]

Published pressure
The cited P Series route lists a maximum operating pressure of 3,000 psig (210 bar) at 100°F (38°C). [S13]
Published materials
The cited P Series route lists stainless steel, brass and Alloy 400 materials. [S14]
  • Hy-Lok P Series in-line plug valves. [S7]

Selection fit: Start with P Series when the cited in-line, throttling and 3,000 psig at 100°F context fit the line. Confirm material, media, temperature and final configuration with Hy-Lok. [S15]

Product range and documented series

Hy-Lok documents NV and SV as needle-valve series in inline and angle patterns. [S8]

  • Hy-Lok P Series in-line plug valves. [S7]Source note: P Series Plug Valve

Procurement fit

For needle valve duties, the documented guidance is to begin evaluation with the NV or SV Series when the cited pattern, material options and published operating envelope fit the application. Final configuration requires confirmation with Hy-Lok regarding medium, pressure, temperature and end connection. For plug valve duties, the documented guidance is to begin with the P Series when the cited in-line configuration, throttling service and 3,000 psig (210 bar) at 100°F (38°C) context suit the line. Final material, media, temperature and configuration require confirmation with Hy-Lok.

Technical capabilities

The NV and SV Series needle valves are documented with material options of stainless steel, brass, Alloy 400 and A105, supplied in inline or angle patterns. The published maximum operating pressure is 6,000 psig / 413 bar at 100 °F, with an operating temperature range of -65 to 600 °F. The P Series in-line plug valves are documented with material options of stainless steel, brass and Alloy 400. The published maximum operating pressure is 3,000 psig (210 bar) at 100°F (38°C).

Markets and applications

The published procurement guidance references duty selection against cited pressure and temperature envelopes without specifying end markets. The needle valve envelope of 6,000 psig / 413 bar at 100 °F and -65 to 600 °F, alongside the plug valve rating of 3,000 psig (210 bar) at 100°F (38°C), is consistent with general instrumentation, process control and laboratory service. Specific end-use sectors, certifications and approvals are not publicly documented in the cited material.

Evidence limitations

The following common buying fields are not publicly documented in the cited material: end connection types and sizes, flow coefficients (Cv), seat and seal materials, leak rates, cycle life, fire-safe certifications, NACE compliance, industry-specific approvals, manufacturing capacity figures, and the relationship between the Busan facility and any other locations. Test reports, third-party certifications, warranty terms, lead times and authorised distributor networks are likewise not publicly documented. Any selection should be confirmed against current Hy-Lok publications.

Editorial summary

Hy-Lok Corporation is a manufacturer based in Busan, Republic of Korea, with documented product coverage in two valve categories: needle valves and plug valves. The needle valve line is represented by the Hy-Lok NV and SV Series, while the plug valve line is represented by the Hy-Lok P Series. Procurement documentation is published for each series, covering material options, pressure ratings and temperature limits. Specifications for additional product lines beyond these documented series are not publicly documented in the cited material.

Compiled prose, not a quotation. It restates facts drawn from the cited rows above and adds none of its own. It is not itself a sourced record, so read the cited sections for the authoritative wording.

Not published in retained sources

These common buyer fields were explicitly outside the retained source coverage for this dossier. They are shown as omissions, not filled with a proxy, a related model or an assumption.

Frequently asked questions

What Needle Valve product is documented for Hy-Lok Corporation?

The retained product material names Hy-Lok NV and SV Series 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 material choices should a buyer compare?

The cited product material records: The cited NV/SV route lists stainless steel, brass, Alloy 400 and A105 options in inline or angle patterns. 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 NV/SV page lists 6,000 psig / 413 bar at 100 °F maximum operating pressure and -65 to 600 °F 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. [S10]

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.
