Subject: draws the diaphragm (10) clear of the main orifice gen. Спецификации по клапанам.Coil voltage disconnected (valve is open): When the supply voltage to the coil (1) is discon-nected, the valve plate (7) are lifted clear of the pilot orifice (9) if there is a differential pressure across the valve. The pressure above the diaphragm (10) drops as the pilot orifice is larger than the equalizing orifice. Therefor the diaphragm is lifted clear of the main orifice (12). If there is no differential pressure across the valve, the opening spring (5) *draws the diaphragm (10) clear of the main orifice* (12) using the assisted lift (8). The valve will be open for as long as there is no voltage to the coil. Coil voltage connected (valve is closed Большое спасибо.
