Uygulama ve seçim rehberliği

This is a small-diameter (DN15-DN50) cryogenic isolation execution; larger cryogenic lines need the wider gate family or dedicated cryogenic executions. Match the class rating (up to Class 800) to the system design pressure and verify that the -80 to +80 C window covers the actual gas and ambient duty, including warm-up transients.

Sık sorulan sorular

Which media is this execution rated for?

The page states O2, N2, Ar and LNG as applicable media between -80 and +80 C, with wetted parts in SS304/SS316/SS304L/SS316L, PTFE packing and a PTFE disc face ring.

What sizes and ratings are covered?

DN15 to DN50 at PN16/PN25/PN40/PN64 and Class 150/300/600/800, with a full NPS 1/2 to 2 dimension and weight table on the page.

Why a gate valve for cryogenic service?

Full-bore wedge shutoff avoids the tortuous flow path of globe executions and keeps pressure drop low on gas distribution; austenitic stainless bodies retain toughness at cryogenic temperature where carbon steel would embrittle. Confirm extended-bonnet length against pipeline insulation at quotation.

Sipariş ve dokümantasyon

Dokümanlar

İhtiyacınız olan dokümantasyon setini talep ile birlikte isteyin — bu icra için tipik kalemler (malzeme sertifikaları, listelenen denetim standardına uygun test raporları, boyut çizimleri) teklifte teyit edilir ve onunla birlikte tedarik edilir.

Teklif

Teklife hazır bir talep şunları belirtir: nominal boyut ve basınç sınıfı, gövde ve yatak malzemesi tercihi, uç bağlantısı, tahrik ve sıcaklıkla birlikte görev ortamı. Bu sayfadaki tipik değerler kıyaslama referans aralıklarıdır; bağlayıcı değerler teklifte teyit edilir.

Numune ve tedarik

Tedarik şartları, sipariş adetleri ve teslim süresi sipariş başına kararlaştırılır — talep ile birlikte varış ülkesini ve gerekli takvimi belirtin.

Depolama ve sevkiyat

Vanaları yatakları ve sızdırmazlık elemanları UV, ozon ve deformasyondan korunacak şekilde depolayın, uç yüzey koruyucularını montaja kadar takılı tutun; elastomer veya PTFE yataklı icralarda uzun süreli açık alanda depolamadan kaçının — yatak bileşikleri doğrudan güneş ışığında ve don koşullarında en hızlı yaşlanır.
