Title (EN) FLOW RATE CONTROLLER FOR HIGH FLOW RATES AND HIGH PRESSURE DROPS
(FR) RÉGULATEUR DE DÉBIT POUR FORTS DÉBITS ET FORTES CHUTES DE PRESSION
Abstract: front page image
(EN)A flow rate controller is disclosed that maintains constant flow rate with changes in pressure drop across the valve by maintaining a constant pressure drop across a restrictor with the aid of a spring balanced piston that mates a cone to a seat to dissipate the majority of pressure drop across the valve.
(FR)L'invention concerne un régulateur de débit qui maintient un débit constant en présence de variations de la chute de pression à travers la soupape en maintenant une chute de pression constante à travers un étrangleur à l'aide d'un piston équilibré par ressort qui accouple un cône à un siège pour dissiper la majorité de la chute de pression à travers la soupape.
