Title
(EN) ELECTRIC FLOW CONTROL VALVE
(FR) VANNE DE RÉGULATION ÉLECTRIQUE DE DÉBIT
Abstract
(EN) Various flow control valves are provided. A flow control valve can include an electro-hydraulic actuator (EHA) and an internal piston. A flow control valve can include an electro-hydraulic pump (EHP). The EHP can be operably coupled to the choke via multiple actuation pistons or an internal sleeve.
(FR) L'invention concerne diverses vannes de régulation de débit. Une vanne de régulation de débit peut comprendre un actionneur électrohydraulique (EHA) et un piston interne. Une vanne de régulation de débit peut comprendre une pompe électrohydraulique (EHP). L'EHP peut être accouplée fonctionnellement à la duse par l'intermédiaire de multiples pistons d'actionnement ou d'un manchon interne.
