게이트 밸브는 파이프라인의 유체 흐름을 완전히 차단하거나 허용하는 밸브 유형입니다. 유량 조절보다는 개폐 제어용으로 주로 설계되었습니다. 밸브가 완전히 열리면 게이트가 완전히 들어 올려져 압력 강하를 최소화하면서 원활한 흐름을 보장합니다. 닫히면 게이트가 완전히 밀폐되어 흐름을 완전히 차단합니다. 게이트 밸브는 밸브가 장시간 완전히 열리거나 완전히 닫힌 상태로 유지되는 시스템에서 가장 효과적입니다. 부분적으로 열린 게이트가 진동하여 마모를 유발하고 밸브를 손상시킬 수 있으므로, 유량 조절용으로는 적합하지 않습니다. 게이트 밸브는 견고한 구조와 높은 압력 및 고온을 견딜 수 있는 능력 덕분에 급수 시스템, 석유 및 가스 파이프라인, 산업 분야에서 널리 사용됩니다. 일반적인 재질로는 주철, 스테인리스강, 황동 등이 있으며, 특정 매체 및 환경에 맞는 맞춤형 옵션이 제공됩니다. 게이트 밸브는 내구성, 견고한 밀폐성, 긴 수명으로 유명하여 많은 중장비 응용 분야에서 선호됩니다.
