더블 오프셋 버터플라이 밸브
더블 오프셋 버터플라이 밸브는 샤프트를 중심선과 시트 평면 양쪽에서 벗어나게 배치하므로, 개방 시 디스크가 시트에서 거의 즉시 떨어져 나와 동심원 설계 대비 마찰 마모가 급감합니다. 범위는 DN50~DN600, PN10~PN63 / Class 150~Class 1500의 웨이퍼 단자로, 구상주철·WCB·SS304/SS316 바디, 알루미늄 청동까지의 대응 디스크, SS410 시리즈 스템, 스테인리스+그라파이트 씰의 13Cr~코발트-크롬 경면 합금 바디 시트, 기어 또는 액추에이터 조작을 제공합니다. 설계는 API 609 / DIN 2559 / EN 593을 따르며 페이스 투 페이스는 ASME B16.5 / DIN3202 F4 / EN558-1, 시험은 API 598입니다. 선정은 오프셋 시트 설계에 대한 등급, 온도에 대한 시트 조합, 접합 플랜지에 대한 웨이퍼 길이에 따라 결정됩니다.

주문·서류
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.
