Title
(EN) PILOT-OPERATED PRESSURE REGULATOR
(FR) RÉGULATEUR DE PRESSION ACTIONNÉ PAR PILOTE
Abstract
(EN)
A pressure regulator is configured for better accuracy and response times at higher inlet pressures. These configurations may integrate two-path control with a pressure-balanced plug. The two-path control may leverage a pair of pilot valves, one with a fixed differential pressure and the other with a variable differential pressure. In one implementation, the device is plumbed so that downstream pressure is sensed at both the actuator and the variable differential pressure pilot valve.
(FR)
Un régulateur de pression est conçu pour une précision et des temps de réponse meilleurs à des pressions d'entrée plus élevées. Ces configurations peuvent intégrer une commande à deux voies avec une prise équilibrée en pression. La commande à deux voies peut tirer parti d'une paire de vannes pilotes, l'une avec une pression différentielle fixe et l'autre avec une pression différentielle variable. Dans un mode de réalisation, le dispositif est raccordé de telle sorte qu'une pression aval est détectée à la fois à l'actionneur et à la soupape pilote à pression différentielle variable.
