A fluid flow control device of the type wherein piezoelectric spring-like benders operably are associated with impacting members, each capable of deforming a membrane to control flow past a valve seat upon change in the electrical condition of the benders. Each bender and impacting member is isolated from the fluid by the membrane. The benders may be mounted individually arranged side-by-side for multiple use or can be grouped in a comb-like configuration. A mounting is provided for the benders which permits the force exercised on the impacting member by the free end of the bender to be adjusted and maintains the electrical isolation of the benders one from the others. The mounting as installed provides a stationary or an adjustable fulcrum point and a clamping member cooperating with the fulcrum for fixing the adjustment. The mounting maintains the free end of the bender centered over the impacting member, enables initial deflection adjustment and further provides for electrical connection of the benders with a fixed receptacle. Where required, compensation is afforded for any differences in thickness between the assembled benders and the receptacle.
