Adapt the choke to the operating environment

With multiple trim options to suit changing conditions, the multitrim chokes accommodate a wide range of oilfield production, flowback, injection, standard, and severe service operations. The modular design and easily interchangeable trim styles provide chokes with enhanced versatility. Adapting the choke valve for different modes of actuation does not require choke disassembly, minimizing production downtime.

Improve erosion resistance

Chokes are frequently exposed to erosive wear because of sand and other particles in the production fluids. If left unattended, washouts and choke failures can result, endangering personnel, environmental safety, and production. Multitrim chokes offer full trim interchangeability, enabling planned maintenance for increased uptime. A replaceable needle tip and external sleeve trim further facilitate maintenance.

Enhance production efficiency and reduce formation damage

Changing trims saves the time and cost associated with purchasing a different type of choke when well conditions change. The multitrim chokes have a significantly extended service life with enhanced controllability due to innovative trim design and the use of advanced materials. The result is more efficient production and less formation damage.
