The Adjustable and Positive Chokes are designed and manufactured in accordance with API 6A, for pressures up to 10,000 PSI (700 bar).
These chokes are available in a large sizes range, and with various trims depending upon customer requirements.
The products are designed to perform according to the requirements of PR1 Performance Requirement Level and, on request, PSL1, PSL2 and PSL3 Product Specification Levels.
By means of a conversion kit, the adjustable type choke can very easily be converted to positive type choke. A wing union cap interchangeable with the adjustable type allows quick replacement of the choke bean.
Dimensions beyond range of afore mentioned table may be offered on request.
