Evidence scope

The retained official product route documents: LESER documents Type 441 IC as a full-lift safety relief valve. This dossier uses that cited route as the editorial scope. [S7]

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. [S9]

Procurement fit

Type 441 IC is documented for set pressures between 0.1–40 barg. Service boundaries are gas and liquid to 40 barg and steam to 32 barg. The cited selection notes require the engineer to verify that the chosen duty, including phase, pressure, and temperature, falls inside these limits before ordering. Material, connection, capacity, and final code must be confirmed directly with LESER, as the documented route does not enumerate these parameters.

Technical capabilities

The published set-pressure range for Type 441 IC is 0.1–40 barg. The valve is a full-nozzle, full-lift design within the safety relief valve category. Stated service limits are 40 barg for gas and liquid duties and 32 barg for steam. Anything beyond these stated values, including temperature limits, orifice size, inlet and outlet sizes, body material, and applicable design codes, is not publicly documented in the cited route.

Markets and applications

The cited Type 441 IC route covers gas service, liquid service, and steam service, with pressure ceilings of 40 barg for gas and liquid and 32 barg for steam. No specific industry sectors, end users, or application examples are listed in the documented facts. Geographic distribution, installed base, and reference projects are likewise not publicly documented within the scope of this entry.

Evidence limitations

Common buying fields not covered by the documented route include body and trim material, inlet and outlet connection sizes and types, orifice letter or area, certified capacity at the relevant set pressure, applicable design codes, temperature limits, NACE compliance, fire-safe certification, and leakage class. These items are not publicly documented in the cited specification. Pricing, lead time, authorised distributor list, and warranty terms are also not publicly documented.

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.
