PF NORVAL <\/strong>R\u00e9gulateurs de pression de gaz \u00e0 action directe<\/strong><\/p>\n

Le NORVAL est un r\u00e9gulateur de pression aval, auto actionn\u00e9, \u00e0 ressort pour les applications moyenne et basse pression. Il convient aux fluides gazeux, non corrosifs, pr\u00e9alablement filtr\u00e9s.<\/p>\n

Sa conception de vanne \u00e9quilibr\u00e9e donne une r\u00e9ponse rapide aux conditions de fonctionnement variables, ce qui la rend particuli\u00e8rement adapt\u00e9e \u00e0 une utilisation lors du service de br\u00fbleurs ON-OFF et dans tout processus industriel o\u00f9 vous avez un changement rapide du d\u00e9bit.<\/p>\n

Its features of good accuracy of regulation, even in presence of significant upstream pressure changes and\/or flow rate, which makes the Norval regulator also particularly suitable for use in natural gas gate stations and industrial and commercial applications.<\/p>\n

Le d\u00e9tendeur NORVAL, dans sa version de base, est class\u00e9 comme d\u00e9tendeur \u00e0 d\u00e9faut d'ouverture (Fail to Open). Il s'agit v\u00e9ritablement d'une conception TOP ENTRY, qui conf\u00e8re au r\u00e9gulateur des avantages de gestion, par exemple la possibilit\u00e9 d'effectuer une maintenance compl\u00e8te sans le retirer de la tuyauterie connect\u00e9e.<\/p>\n
