Circulating and Reversing Valves

Annulus Reclosable Circulating Valve

The annulus reclosable circulating valve (ARCV) has the ability to circulate or reverse circulate multiple times for cushion spotting or desired well-kill operations.

Single-Shot Reversing Valve

The single-shot reversing valve (SHRV) operates by applying annulus pressure to burst a rupture disk. Once actuated, the reversing ports are locked open. The SHRV is typically opened at the completion of the drillstem test (DST) to reverse out fluids produced during the test.

Multicycle Valve

The multicycle circulating valve with lock (MCVL) is a reclosable valve operated by tubing pressure and is used for spotting fluids and nitrogen.
