The unregulated choke (DN) is used to regulate the mode of operation of the well. Regulation of well operation is carried out through the use of choke-nozzles of different diameters (for example: 6, 7, 8, 9, 10, 11, 12, 15, 18 mm or others), to ensure the desired mode of operation of the well in the choke is installed choke-nozzle with the required diameter.
The main advantages: the parts carrying out regulation are made of wear-resistant and corrosion-resistant materials, the presence of a quick-release connection body - cover facilitates the conditions for changing the choke, the presence of a port for pressure relief increases the safety of work.
