How did the pneumatic symbol of double acting pneumatic ball valve come from? The equipment shall be equipped with appropriate equipment support when using pneumatic butterfly valve.
When selecting pneumatic butterfly valves for equipment, the model and quantity shall be confirmed first. It is necessary to ensure that the dynamic load of the equipment can be accepted and the vibration transmission coefficient (ratio of transmission force to interference force) is small. When applying pneumatic butterfly valves, the following factors shall be considered:
1. Be able to provide the required quantity;
2. Be able to accept the load of rules;
3. Able to accept changes in temperature and other environmental conditions (temperature, corrosive fluid, etc.);
4. Have certain valve characteristics;
5. Meet the requirements of equipment using pneumatic butterfly valves for valve volume and quantity.
