295,994. Akt.-Ges. Brown, Boveri, et Cie. Aug. 22. 1927, [Convention date]. Closure members. double. beat. - In double-beat lift valves for operation by servo-motors provision is made for stabilizing or balancing the valve by means of the reaction of the energy of velocity of the fluid thereby enabling a valve to be produced with the upper member of a laver diameter e than the lower d so that the valve can be assembled without the use of an upper split seating. For this purpose a baffle or deflecting ring f is disposed on the valve member between the closure surfaces or on a tubular part depending below the lower closure surface.
