H2 Needle and Seat Choke

With pressure ratings to 15,000 psi, Cameron H2 needle-and-seat chokes handle standard, erosive, and corrosive service.

Available configurations

• Positive chokes provide a fixed flow condition with a large selection of available bean sizes and types

• Adjustable chokes provide variable flow rates but can be locked into position if a fixed flow rate is required

• Combination bean and seat converts the adjustable choke to a positive/adjustable choke for bringing on the well slowly with the adjustable feature.

Once the desired flow rate is reached, the choke can be operated as a positive choke. This reduces wear on the wing or master gate valves because they are not used to control flow. In every application, the H2 choke delivers long life and low maintenance.
