Variable Orifice Injection Safety Valves (VOi) allows you to inject more fluid at lower cost. The VOi is the first choice for any new injection well (single or multi-zone), but can be retrofitted in any existing well. The VOi series are autonomous operating valves that have all the benefits of running a conventional downhole injection safety valve but none of the drawbacks. A very low pressure differential throughout the entire operating range is maintained, making the VOi virtually “invisible” in the injection system, as the orifice opening changes and directly responds to changes in flow rates. That means more fluid injected at lower cost. Succeed with us!
