1. Attentions should be paid when pipe resistance is large or a large amount of blow-off air rate is required. Insufficient blow-off air may cause troubles. Make sure to evaluate PISCO products by actual system. 2. The coil in a pilot valve generates heat under the following ① - ③ conditions. Heating may be a cause of dropping life cycle, malfunctions and burn or may affect negatively on peripheral machines due to the heat. -
