Computer Controlled Variable Pressure Reducing/Shut-Off Valve for Aircraft ECS 851360

The present paper reports the development results of a computer controlled variable setting pressure reducing valve (VPRV) designed by Microtecnica and suitable for operation in the latest generation of aircraft ECS.The valves features a double element design, allowing a total independent operation (Shut-Off section and pressure reducing section) offering thereby high reliability and safety. The valve provides wide capability of varying the pressure set point by action of an electric servo and allows considerable weight and energy saving in the ECS design.Results of Experimental Tests performed in the development program are presented in detail.
