The H2 adjustable choke valve is a needle and seat choke that is used to keep fluid or gas flowing at a specific required rate. The flow can be adjusted by the needle and seat and then locked when the flow rate is reached.

Configurations and Components

Our type H2 needle and seat style adjustable choke comes in different configurations. All of the adjustable chokes have four components:

●Needle - The needle is made from 410 or 17-4 PH Stainless Steel and is manufactured with a carbide tip.

●Seat - The seat is also 410 or 17-4 PH SST and has a carbide lining insert.

●Bonnet assembly

●Body - The body can consist of flanged ends from 2-1/16” through 4-1/16” or with line pipe connections.

The minimal components in the H2 choke make both operation and maintenance easy and convenient. The adjustable choke can also be quickly converted to a positive choke by replacing the seat with a fixed flow bean and the bonnet assembly with a wing nut and plug.
