Orientação de aplicação e seleção

Select this execution where small-bore lines need a through-conduit shut-off at class ratings far above what a cast compact body carries: match the bonnet design to pressure (bolted for general service, pressure seal toward the top of the Class 150-4500 envelope), the forging to line temperature and medium, and the end connection to the piping standard — socket-weld and threaded ends for compact instrument-grade pipework, RF/RTJ flanges or butt-weld ends for permanent plant installation.

Perguntas frequentes

What standard governs compact forged gate valves?

The benchmark execution is built to API 602, the compact forged-body gate valve standard, with both bolted bonnet and pressure seal bonnet constructions available so the same envelope serves general plant service through Class 2500-class and beyond, up to Class 4500.

Which sizes and pressure classes does this execution cover?

NPS 1/2 to 2 (DN15 to DN50) at ASME Class 150 through 4500 (PN16 to PN760) — the full compact forged envelope, where the forged body carries pressure classes that cast small-bore bodies cannot.

How do I choose body material and end connection?

Body materials span carbon steel for general service, low-temperature steel for cold service, stainless and duplex stainless for corrosion, and alloy, nickel-base or titanium-alloy forgings for severe service. End connections — RF flange, butt-weld, RTJ, socket-weld or NPT thread — follow the plant piping standard and the maintenance philosophy (welded ends for integrity, threaded or socket ends for compact replacement).

Encomenda e documentação

Documentos

Solicite com o pedido o conjunto documental de que precisa — os itens habituais para esta execução (certificados de material, relatórios de ensaio segundo a norma de inspeção indicada, desenhos dimensionais) são confirmados e fornecidos com a cotação.

Cotação

Um pedido pronto para cotação indica: dimensão nominal e classe de pressão, preferência de materiais do corpo e da sede, ligação terminal, acionamento, e o fluido de serviço com a sua temperatura. Os valores típicos nesta página são gamas de referência; os valores vinculativos são confirmados na cotação.

Amostra e fornecimento

As condições de fornecimento, quantidades encomendadas e prazos são acordados por encomenda — indique o país de destino e o calendário requerido com o pedido.

Armazenamento e expedição

Armazene as válvulas com sedes e vedantes protegidos de UV, ozono e deformação, mantenha as proteções das faces de junção até à instalação e, nas execuções com sede em elastómero ou PTFE, evite o armazenamento prolongado ao ar livre — os compostos das sedes envelhecem mais depressa à luz solar direta e em condições de congelamento.
