A diaphragm operated fluid logic valve device utilizing proportionate pressure areas on opposite sides of the diaphragms for obtaining differential pressures thereacross and, therefore, snap action during transition from one state to another, said valve device structurally including interface characteristics so as to be adaptable to a wide range of pressures and, therefore, directly applicable in a high pressure system without the use of a separate interface device, and being capable of integration with a variety of means, such as a low pressure fluidic signal, a small solenoid, or a Belleville spring to provide an interface function for piloting the control pressure functions of the valve device. |
