Our MasterChoke H2 type profile is fully interchangeable with those of other manufactures of the same H2 type profile. This design is time-proven, and it has been employed in many service applications within the industry.
Chokes maybe ordered in either positive or adjustable models. Each model utilizes a hammer union type connection, which facilitates the quick change out of flow beans and trim, while the choke body remains installed in the line. This equates to less down time and more production time during trim change out.
Type H2 Positive & Adjustable Chokes
The MasterChoke line of chokes is ideally suited for a broad range of applications, including wellhead trees, production manifolds, choke and kill manifolds, flow back systems, clean-up operations and various injection systems.
