응용·선정 가이드
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.
자주 묻는 질문
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.

서류
문의 시 필요한 서류 세트를 요청해 주십시오 — 이 구조의 일반적인 항목(재질증명서, 명시된 검사 표준에 따른 시험 성적서, 치수 도면)은 견적 시 확인되어 함께 공급됩니다.
견적
견적에 바로 쓸 수 있는 문의에는 다음을 명시합니다: 공칭 구경과 압력 정격, 바디·시트 재질 선호, 접속 방식, 조작 방식, 온도를 포함한 사용 유체. 이 페이지의 전형값은 벤치마크 참조 범위입니다; 구속력 있는 값은 견적 시 확정됩니다.
샘플·공급
공급 조건, 발주 수량, 납기는 주문별로 합의합니다 — 문의 시 납품 국가와 필요한 일정을 알려 주십시오.
보관·운송
밸브는 시트와 씰을 자외선, 오존, 변형으로부터 보호하여 보관하고, 설치까지 단면 보호캡을 유지하십시오; 탄성체 또는 PTFE 시트 구조는 장기 야외 보관을 피하십시오 — 시트 재료는 직사광선과 동결 조건에서 가장 빨리 노화됩니다.
