VALVULA DE RETENCAO E DE EXPANSAO COMANDADA POR FLUIDO E INSTALACAO DE ESTERILIZACAO A TEMPERATURA ULTRA-ELEVADA

摘要

In order to regulate the pressure of a liquid in a pasteurizer or sterilizer operating at a high temperature, the valve comprises two chambers separated by a diaphragm integrally connected to a valve pin. …The pressure on the liquid to be treated side is at all times greater than that of the actuating air by virtue of the fact that the surface on which the compressed air acts is greater than that with which the liquid is in contact. This makes it possible to keep the installation sterile even in the event of faulty sealing of the diaphragm. …The valve is particularly suited to ultra-high-temperature sterilizers with direct injection of steam. ……
