Abstract

Se proporciona una PRV, que comprende una entrada, una salida y un sistema regulador de presión entre estas para mantener una presión de ajuste en la salida. La PRV comprende además un sistema de selección configurado para seleccionar entre las dos presiones de trabajo en función de la presión del fluido en la entrada de la PRV, y para dirigir el sistema regulador de presión para mantener la presión de ajuste en la salida a la presión de trabajo seleccionada. El sistema de selección comprende un transductor de movimiento de presión para dirigir la presión de ajuste cuando está en comunicación de presión con la entrada, y una válvula auxiliar que tiene una entrada auxiliar en comunicación de presión con la entrada y una salida auxiliar en comunicación de presión con el transductor de movimiento de presión. La válvula auxiliar se configura para establecer una comunicación de presión entre su entrada y salida cuando la presión en la entrada atraviesa un umbral predeterminado.
