A multiple valve assembly comprising: a body including a plurality of valves with a corresponding plurality of valve seats; at least a first one of said valves including a laterally flexible valve stem having a valve element at one end moveable into and from engagement with a corresponding valve sea

A multiple valve assembly comprising: a body including a plurality of valves with a corresponding plurality of valve seats; at least a first one of said valves including a laterally flexible valve stem having a valve element at one end moveable into and from engagement with a corresponding valve seat by lateral deflection of said valve stem to open and close a corresponding valve; at least one independently actuable one of said valves including a valve rod having a valve element at one end moveable 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 each independently actuable valve secured to the opposite end of the corresponding valve rod to move the latter axially; said body containing a bore traversed by each valve stem and valve rod; and an operating means for said at least one first valve moveable in said body bore for exerting lateral deflecting forces on said flexible valve stems only.
