Abstract

Un accionador electrico (10) es particularmente adecuado para accionar una valvula de cabezal de pozo (12) para regular el flujo de gas natural desde un pozo de produccion (16). El accionador electrico (10) puede ser accionado usando el suministro de energia local (24) existente en los sistemas de valvula de cabezal de pozo, tipicamente un panel solar (24) y una bateria (26). El accionador electrico (10) puede incluir un tren de reduccion de engranes (76), un freno (78) y un cierre de entrada manual (80) con proteccion de embrague. El accionador electrico (10) puede ser configurado en tres modos de operacion diferentes que proporciona una posicion predeterminada tras la perdida de potencia que incluye desviacion de fallas fija, desviacion de fallas abierta y desviacion de falla cerrada.
