AUTOCHOKE pressure-balanced drilling choke

The AUTOCHOKE pressure-balanced drilling choke provides automatic and precise high-pressure control at 3,000 psi, 10,000 psi, and 15,000 psi. The choke is ideally suited for pressure-intensive underbalanced and managed pressure drilling (MPD) applications. The choke automatically regulates casing pressure under all conditions, including during mud pump startup or shutdown and when making and breaking drillpipe connections.

The M-I SWACO AUTOCHOKE unit provides automatic, precise pressure control.
