Choke Valve

Exclusive US distributor for New Star.
More Information.

Design Standard

Choke valves are used to control flow rate and reduce pressure for processing of produced fluids farther downstream. Effective chokes reduce the likelihood of damage to downstream equipment, support longer lasting production timespans, and alleviate stress from field operators by keeping them away from the wellhead.

Our chokes are also economical and provide the lowest total cost of ownership in the industry. As a global manufacturer and supplier of chokes for the oil and gas production market, we can provide a fit-for-purpose solution for any application.

Selecting the proper trim for your application and environment is crucial and can help avoid expensive damage such as erosion and corrosion.
