탑 엔트리 볼 밸브

탑 엔트리 볼 밸브는 상부 커버를 통해 정비하므로 밸브를 라인에 둔 채로 시트, 씰, 볼을 점검하거나 교체할 수 있습니다 — 공정 및 파이프라인 용도에서 인라인 점검이 가능한 차단의 정비상 이점입니다. 시리즈는 PN16~PN250 및 Class 150~Class 2500에서 DN50~DN700에 이르며, WCB/LCB 주조 또는 CF8/CF8M 스테인리스 바디, PTFE 또는 RTFE 시트, RF·RTJ·버트 용접 단자, API 607 및 API 6FA 파이어세이프 설계를 제공합니다. 설계 표준은 API 6D, API 608과 함께 MSS SP-72, ASME B16.34, ISO 17292를 아우르며, 시험은 API 598, API 6D, EN 12266, ISO 5208을 커버합니다. 핸드휠, 기어, 전동, 공압 조작이 모두 제품군에 포함됩니다.
