Two-cycle ball valve

Dual Shot Ball Valve

Description

The Dual-Shot Ball Valve is an annular rupture disc controlled ball valve that can be set to have one or two individual ball cycles. The Dual-Shot Ball Valve can be run in-hole in either the open or closed position.

In the single cycle configuration, the Dual-Shot Ball Valve can be used as a tubing string pressure test valve, or as a safety shut in valve in HPHT wells where a secondary down hole barrier is required. The dual-cycle configuration provides downhole test valve with one shut-in cycle for a pressure build up, and the ability to re-open for an additional flow period or well kill procedures.
