Precautions for buying valves
Gate valve: suitable for fully open or fully closed pipes 2. Shut-off valve: used for shut-off and throttle medium 3. Ball valve: quick opening and closing, good sealing 4. Butterfly valve: suitable for switch control of large-caliber and low-pressure pipes 5. Check valve: prevent the backflow of the medium 6. Control valve: adjust flow, pressure, temperature, and liquid level.
밸브로 유입되는 유체는 밸브의 수명에 큰 영향을 미칩니다. 유체마다 부식성, 마모, 압력, 온도 등이 다르기 때문에 밸브에 적합한 재질을 선택하는 것은 밸브 손상을 방지하는 데 매우 중요합니다.
Caliber size, pressure level size, and product quality meet international standards.
밸브의 연결 방식은 배관 시스템의 연결 방식과 일치해야 합니다. 이는 설치 편의성과 사용 중 안전을 보장하기 위함입니다.
Drive mode: manual, automatic, semi-automatic, electric, pneumatic, and other actuators.
Flow mark: Whether there is a clear flow mark to prevent installation errors.
Good reputation, completely qualified manufacturers or suppliers. Product quality standards and certification certificates, whether to provide quality assurance services and installation guidance, etc.
