In order to allow those control valves to guarantee a long service life in extremely harsh environments. The experts used a closed technology to manufacture 316 hydraulic seamless steel rings in the interior and used a pipeline engineering group and pneumatic valves.
This control valve can also be equipped in a hydraulic tank to provide the correct position for pressurization, process control and reinjection, and to adjust and defend against potential hazards in the main valve section. This equipment can also achieve the effect of preventing weather hazards through the electrochemical connection between the cable and the terminal equipment that Eexd freezes.
Valves can withstand extreme environments
Electro-hydraulic actuators Midland-ACS has developed self-contained electro-hydraulic pipeline actuators controlling valves ranging in size from 8 inches to 32 inches. The valves have been especially designed to work in the –290C to +400C operating temperature range along the BTC (Baku-Tibilisi-Ceyhan) crude oil pipeline operating from the Mediterranean Ceyhan terminal through 3 countries to the Caspian Sea.
In order for the actuators to withstand the harsh and extreme conditions they would be subject to and also to ensure longevity, specialist sealing technology and in-house manufactured 316 stainless steel hydraulic cylinders, pipework and pilot valves were used.
The actuator assembly also includes a hydraulic reserve tank used for pressure, flow control and re-injection, providing accurate positional, modulating, and fail-safe control of the larger main valve. Weather protection is provided for the electrical connections by using Eexd rated cables , glands and termination.
Midland-ACS is the authority to produce electronic hydraulic control valves, and recently they have developed valves that are inclusive. This valve controller ranges in size from 8 inches to 32 inches. The valve is specifically designed for operating temperatures ranging from -290C to +400C, which is suitable for use in the crude oil channel transport process from the Mediterranean Ceyhan terminal to the extreme environments of the Caspian Sea via three countries (Baku-Tibilisi-Ceyhan).
