MPC Series The MPC series of chokes are high pressure chokes that provide remote actuation while handling severe erosive service with high pressure drops across the seat and internally monitors the wear of the choke trim. The MPC series has a reputable performance history for handling severe choke applications worldwide. Our MPC External Sleeve can be customized for extreme temperature conditions as low as -150°F to as high as 575 °F.

Features include the Wear Monitor which reduces the chance of a washout by facilitating seat seal and seat wear leakage detection. Like the CVC-ME design, the trim is an external sleeve cage suitable for high pressure drops.

However, in MPC models, the rated capacity or curve characteristic can be modified by exchanging only the seat assembly. This can greatly reduce the quantity of spares in inventory. Our MPC-S model boasts the same history of proven performance worldwide as the MPC - External Sleeve Choke with the difference being that this is the internal cage version. It is rare in the industry to find large internal cage style chokes suitable to high pressures, however this model can be customized to sustain up to 20,000 psi. Like the MPC-External Sleeve, this design also includes the Wear Monitor which reduces the chance of a washout by facilitating seat seal and seat wear leakage detection. Furthermore, MPC-S chokes also allow for modification of the rated capacity or curve characteristic by a simple swap of the seat assembly. Like the CVC-MP, MPC-S models are recommended to flow a large volume of fluid with superior controllability.

Our MPC In-Line has an in-line body for cases where it best suits our customer's piping needs. Components are interchangeable between angled bodied MPCs and in-line MPCs. Designed to extend service life, operate safely and cost effectively, this series of chokes has increased the efficiency of operations for years.

The use of NOV’s wear monitor, which reduces the chance of a choke washout and eliminates unnecessary well shut-ins when inspecting the condition of the trim. NOV’s cage trim design utilizes the principle of flow impingement to dissipate the energy in the flow stream resulting in a reduction in cavitational and erosional wear, while leading to superior performance.
