Selection of flexible electric butterfly valve:
1. Pressure. It shall be selected according to the pump lift. Generally, the working pressure of common joints is 0.6, 1.0, 1.6 and 2.5 Mpa. 2. Temperature. Select according to the medium you transport, generally - 15 ℃~115 ℃, especially - 30 ℃~160 ℃. 3. Media. Common connector media: air, compressed air, water, seawater, hot water, oil, acid, alkali, etc. 4. For more professional ones, the bursting pressure and vacuum degree should also be considered.
