Masoneilan Control Valve Sizing Handbook 5 DRESSER VALVE DIVISION Masoneilan Liquid Flow Equations Cv = valve flow coefficient N=numerical constants based on units used (see Table 1) Fp = piping geometry factor (reducer correction) FF = liquid critical pressure factor = 0.96 0.28 pv pc FL = liquid pressure recovery factor for a valve FLP = combined pressure recovery and piping geometry factor for a valve with attached fittings Capacité des vannes de réglage Free La caractéristique principale d'une vanne de réglage est son coefficient de débit. Ce critère introduit en 1944 par le constructeur US de vannes Masoneilan avec le symbole "Cv", correspond au débit maximum (en Gallon US) d'eau pouvant la traverser en 1 minute pour une chute de pression de 1 psi (livre par pouce carré). Vanne automatique — Wikipédia La vanne automatique ou vanne de régulation, est un organe qui relève de la régulation industrielle des procédés physico chimiques. Elle est commandée par un actionneur dont les variations continues de la position modifient la taille de l'orifice de passage du fluide. De cette façon, la chute de pression aux bornes de la vanne est modulée lors du passage d'un fluide, avec pour ... Masoneilan* 35002 Series Camflex* II Valves 2018 Bae He a GE an. ll i eeve.
