에센트릭 플러그 밸브

에센트릭 플러그 밸브는 둥근 플러그를 오프셋 시트로 스윙시켜 폐쇄 위치에서만 캠 작동으로 확실히 밀어 붙입니다 — 매 행정에서 시트가 긁히지 않고 닦이므로, 직선 리프트 플러그가 시트를 갉아먹을 수 있는 모래·섬유·스케일 함유 물 및 하수 서비스에서 밀폐를 유지합니다. 범위는 NBR 또는 EPDM 시트를 갖춘 주철 RF 플랜지 사양, DN15~DN400(1/2~16인치), PN10~PN16 및 Class 150, 수동·공압·전동 조작입니다. 바디 및 보닛은 A126 B, GG25, FC20, A536, A395, GGG40 또는 GGG50 등급으로 플러그도 동일 범위이며, 그라파이트 또는 PTFE 패킹, 숏·레귤러·벤추리 포트 패턴, 나선 권 개스킷의 볼트 체결 보닛, 안티스태틱 설계, 분사 방지 스템, 소프트 시팅이 구성에 포함됩니다. 서비스는 -29~120°C의 물, 하수 및 오수입니다. 선정은 유체에 대한 시트 엘라스토머, RF 플랜지 등급, 맨홀 또는 플랜트의 조작 방식에 따라 결정됩니다.
