Solenoid valve and its application to an apparatus for delivering cryogenic liquid and a packaging plant |
摘要 |
A solenoid valve is provided that includes a valve body (14) having an inlet duct (18), an outlet duct (24) and a plurality of sequentially operated solenoid actuators arranged in a circular configuration for selectively bringing these two ducts into communication with each other. The valve body includes at least two separate passages (19, 20) which connect the inlet duct to the outlet duct, and each of the solenoid actuators operates to periodically and selectively close off one of said passages. The solenoid valve finds particular application in inerting and pressurizing bottles containing still liquids with nitrogen.
