프레셔 시일 글로브 밸브

프레셔 시일 글로브 밸브는 보닛 접합부를 관내 압력 자체로 밀폐합니다 — 내부 압력이 높을수록 개스킷 하중이 커지므로, 볼트 체결 보닛이 실용성을 잃는 압력 범위 상단을 이 설계가 담당합니다. 범위는 Class 1500~Class 2500에서 DN50~DN400으로, 바디·보닛·요크·웨지가 A105, F304/316 시리즈 스테인리스, F51/F53 듀플렉스, F11/F22 크롬-몰리브덴 또는 LCB, 스템과 글랜드는 F6a 및 스테인리스 등급, 시트는 코발트-크롬 경면 합금 또는 스테인리스, 스테인리스-그라파이트 개스킷의 그라파이트 및 PTFE 패킹입니다. 단자는 RF, RTJ, 버트 용접, 소켓 용접, NPT에 이릅니다. 설계는 API 602 / BS 5352 / ASME B16.34를 따르며 시험은 API 598 / EN 12266입니다. 선정은 설계 압력에 대한 등급, 용접 단자 규격, 유체에 대한 시트 면에 따라 결정됩니다.
