In a multiple valve assembly having: a body including a plurality of valves with a corresponding plurality of valve seats; a first one of said valves including a laterally flexible valve stem having a valve element at one end movable into and from engagement with a corresponding valve seat by lateral deflection of said valve stem to open and close the corresponding valve; a second, independently actuable one of said valves including a valve rod having a valve element at one end movable into and from seating engagement with a corresponding valve seat by axial movement of said valve rod to open and close the corresponding valve; a valve actuator for said independently actuable valve secured to the opposite end of said valve rod to move the latter axially; said body containing a bore traversed by said valve stem and said valve rod; and operating means for said first valve movable in said body bore for exerting lateral deflecting forces of said flexible valve stem only; the improvement wherein: said valve operating means comprises an operating bar movable longitudinally in said body bore through a given stroke and having clearance openings through which said valve stem and valve rod extend, and means for accommodating said operating bar openings to said stem and to said rod such that the bar exerts lateral deflecting forces on said flexible valve stem only during movement of the bar through said given stroke, said accommodating means comprising uniform bar openings and cooperating shape characteristics of said valve rod.
