Schuifafsluiters · Gesmede Stalen Schuifafsluiters
Compacte Gesmede Schuifafsluiters
De compacte gesmede afsluiter is de kleinbore-, hoogdruk-uitvoering van de afsluiterfamilie: een gesmed lichaam gebouwd volgens API 602, in gebolteerde-strompel- en drukafdichting-strompel-ontwerpen, dekkend NPS 1/2 tot 2 bij ASME Class 150 tot 4500. De benchmark-pagina beslaat koolstofstaal-, lagetemperatuurstaal-, roestvast staal-, legeringsstaal-, duplex roestvast staal-, nikkelbasis- en titaniumlegering-bodies, met RF-, BW-, RTJ-, SW- en NPT-einden en handmatige, pneumatische, elektrische of hydraulische bediening.

Toepassings- & selectieadvies
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.
Veelgestelde vragen
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).

Offerte
Een offerteklare aanvraag noemt: nominale maat en drukklasse, voorkeur voor huis- en zittingsmateriaal, aansluiting, bediening, en het medium met temperatuur. Typische waarden op deze pagina zijn benchmarkreferentiebereiken; de bindende waarden worden in de offerte bevestigd.
Sample & levering
Leveringsvoorwaarden, orderhoeveelheden en levertijd worden per order afgesproken — noem het bestemmingsland en het gewenste schema bij de aanvraag.
Opslag & verzending
Bewaar ventielen met zittingen en afdichtingen beschermd tegen UV, ozon en vervorming, houd de vlakbeschermers op de aansluitvlakken tot installatie, en vermijd bij uitvoeringen met elastomeer- of PTFE-zittingen langdurige buitenopslag — zittingscompounden verouderen het snelst in direct zonlicht en bij vorst.
