Three-inch, four-inch, four-inch x three-inch and six-inch venturis
Whittaker venturis are designed for use in fuelling systems where it is desirable to accurately control the pressure into an airplane fuel system at the underwing nozzle. The venturi provides a convenient point to control pressure and compensate for the pressure loss of the plumbing between the venturi and the underwing nozzle. Thus, in effect, control is achieved at the nozzle by controlling to the desired pressure at the venturi. Venturis are provided with an adjustable mixing valve to allow matching of compensation for a particular system. Venturis are engineered to provide the following features
