Abstract

An improved flip-flop fluid logic circuit device is made from a body block having a through bore and adapted to receive a pair of identical inserts, a composite valve member in between the inserts, pressure responsive diaphragm members for engaging the opposite ends of the valve member to drive the valve between extreme positions within the bore and means for sealing the ends of the bore to retain the operating mechanism. A manual override button is included at each end of the bore to operate the composite valve member.
