체크 밸브 선택 시 고려 사항

When selecting a check valve, factors such as media characteristics, operating pressure, temperature range, and installation space must be considered comprehensively. For example, for low-viscosity media (such as water), ball check valves are the first choice due to their low flow resistance and good sealing performance; while for high-viscosity media (such as oil), swing check valves with a wider flow channel design should be selected to reduce flow resistance. In addition, pressure rating is also a key parameter. Medium-pressure systems (such as 1.6-4.0 MPa) require check valves with stronger pressure resistance, while low-pressure systems (such as ≤1.0 MPa) can use more cost-effective ordinary check valves. Regarding temperature, media ≤120℃ can use check valves with fluoroplastic seats, while high-temperature media (such as >200도)에는 금속 시트가 있는 체크 밸브가 필요합니다. 마지막으로 설치 공간도 고려해야 합니다. 공간이 제한된-애플리케이션의 경우 소형 버터플라이 체크 밸브를 선택할 수 있습니다. 공간이 넉넉한 응용 분야의 경우 보다 유연한 개폐 기능을 갖춘 스윙 체크 밸브를 선택할 수 있습니다.
