    Midland-ACS公司是生产电子油压控制阀的权威机构，最近他们研制出具有我包容能力的阀门。这种阀门控制器尺寸范围从8英寸到32英寸。这种阀门特别设计的操作温度范围是-290C到+400C，这就适用于原油渠道输送过程中，从地中海Ceyhan终端机经由三个国家(Baku-Tibilisi-Ceyhan)到达里海的各种极端环境。
    为了让那些控制阀在极端恶劣的环境下保证较长的使用寿命。专家采用了封闭技术，在内部制造316个水力无缝钢圈，并且运用了管道工程组和气动阀。
    这种控制阀也可以装备在液压储罐中，为加压、流程控制和再注入提供正确的位置,调整和防御主要阀门部份的潜在危险。通过Eexd定格的电缆和终端设备之间的电化联接，这种装备同样可以达到预防天气危害的效果。

Valves can withstand extreme environments
    Electro-hydraulic actuator specialist 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.
