Technical specifications:
Nominal bore diameter, mm: 2.3, 4, 5, 6, 8, 10, 12, 18Installation position: any
Connection version: flange (GOST, RD, API)
Direction of supply of fluid flow: one-sided
Basic advantages:
- unlike choke chambers, where it is necessary to dismantle (install) flanges when replacing chokes, the design of the choke allows the flow area to be changed due to the axial rotation of the valve spool, which has holes of different diameters
- control devices are made of wear-resistant and corrosion-resistant materials, which ensures wear-resistance and long service life of the choke device
- the use of this design allows to minimize the costs of changing the operating mode of the well, eliminate downtime of the well, which provides a significant economic effect
- leak-tightness class DDRD - “A”
