프레셔 시일 게이트 밸브

프레셔 시일 게이트 밸브는 내부 압력 자체가 보닛 시일을 조이는 구조를 사용합니다: 대략 Class 900 이상에서 관내 유체의 압력이 프레셔 시일 개스킷을 보닛 리테이너쪽으로 밀어내어, 고등급에서 볼트 체결 보닛 방식과 달리 밀폐가 악화되지 않고 압력과 함께 강화됩니다. 시리즈는 Class 1500~Class 2500에서 DN50~DN400을 커버하며, 넓은 재질 매트릭스(A105, F304/F316 및 L 등급, F51/F53 듀플렉스, F11/F22, LCB), 코발트-크롬 경면 합금 또는 스테인리스 시트, 그라파이트/PTFE 패킹, RF/RTJ/BW/SW/NPT 단자, 핸드휠 또는 전동 조작을 제공합니다. 시험은 API 598, DIN 3230, EN 12266 및 ISO 5208이 목록에 있습니다.
