Orifice Valves

Each DIAL unit can be configured with orifices selected to match predicted gas injection needs across the well’s full operating life. A six-valve DIAL unit gives up to 64 individually selectable flow rates.

The units include tubing to annulus well integrity check valves. However, these are not sensitive to downhole conditions and are less prone to failure than conventional systems as valve chatter is impossible. DIAL gas lift valves are designed and qualified to an equivalent of API 19 G2.
