Case Study
Russian Oil & Gas Pipeline Project: We supplied over 400 units of our high-end actuators for remote automated control of oil and gas pipelines in Russia. The actuators were required to operate in extremely cold climates with temperature differences and potentially explosive atmospheres. Our DQ series, with EX explosion-proof certification, successfully passed the factory acceptance test conducted by the Russian delegation, providing stable and precise control even at -40°C. This project replaced several traditional European and American brands, marking a breakthrough in the high-end Russian market.
