Blowout Preventers

Simple to use and less maintenance PSS’s Hydraulic Chokes control returns of flowbacks upstream or downstream of manifolds. The main advantage of a PSS hydraulic choke over a regular choke is the ability to open the ID if plugged or bridged off, then resuming operations by reapplying hydraulic pressure, saving time. All our hydraulic chokes are NACE MR0175 compliant and come in all industry standard sizes.
