ABSTRACT:
A hermetically sealed, remotely operable plug valve has a plug that moves between a seated and unseated position in a housing. A cam and cam follower cause the plug to rotate as it moves up and down in the housing. The plug has a transverse opening which interconnects the inlet and outlet for opening and closing the valve when the plug reciprocates between the seated and unseated positions. A solenoid external to the housing drives the plug up and down.
