Function NC Coil voltage disconnected (closed): When the voltage is disconnected, the valve plate (3) is pressed down against the pilot orifice (4) by the armature spring (). The pressure across the diaphragm (5) is built up via the equalising orifice (7). The diaphragm closes the main orifice (6) as soon as the pressure across the diaphragm is equivalent to the inlet pressure. The valve will be closed for as long as the voltage to the is disconnected. Coil voltage connected (open): When voltage is applied to the (), the pilot orifice (4) is opened. As the pilot orifice is larger than the equalising orifice (7), the pressure across the diaphragm (5) drops and therefore it is lifted clear of the main orifice (6). The valve is now open for unimpeded flow and will be open for as long as the minimum differential pressure across the valve is maintained, and for as long as there is voltage to the..coil.armature spring 3.Valve plate 4.Pilot orifice 5.Diaphragm 6.Main orifice 7.Equalising orifice Ordering NC Connection ISO8/ G ½ G ¾ G G ¼ G ½ G Seal material k v - value [m 3 /h] EPDM ) FKM 3) 4 EPDM ) FKM 3) 8 EPDM ) FKM 3) EPDM ) FKM 3) 8 EPDM ) FKM 3) 4 EPDM ) FKM 3) 4 - - - - - - Media temp.
