WFV™ – MP (Multi Position)

Welltec® Flow Valve - for Inflow & Injection Management

Introduction

The Welltec® Flow Valve is a full bore valve that can be used for both production and injection purposes within the lower completion, the rugged design enables rotation during liner deployment.

With specially designed inlets and sealing system, the WFV is qualified to open and close multiple times under differential pressure whilst maintaining flow, from both injection and production scenarios.

The full bore design makes it ideal for intervention-enabled completions and together with Welltec® Annular Barrier providing high pressure zonal isolation, the WFV forms an integral part of the Flex-Well® completion.
