It is not only suitable for medium and low pressure, but also suitable for high pressure.
Globe valves have the following advantages:
1. ساختار ساده، مناسب برای ساخت و نگهداری.
2. The working stroke is small and the opening and closing time is short.
3. عملکرد آب بندی خوب، اصطکاک کوچک بین سطوح آب بندی و عمر طولانی.
شیرهای گلوب دارای معایب زیر هستند:
