The Democratic Republic of Congo (DRC) stands as a titan of industrial potential in sub-Saharan Africa. As the world's leading producer of cobalt and a top-tier copper miner, the DRC's industrial sector is undergoing a massive transformation. This growth necessitates robust infrastructure, particularly in fluid management and flow control systems. Butterfly valve suppliers and factories are becoming critical partners in the DRC's journey toward modernization.
In the copper-rich Katanga region and the burgeoning Lualaba province, mining operations require high-durability valves to handle abrasive slurries and corrosive chemicals used in leaching processes. Butterfly valves, known for their compact design and efficient quarter-turn operation, are the preferred choice for large-scale mining pipelines. Our UD Series hard-seated butterfly valves are specifically engineered to withstand these harsh environments, offering a longer service life compared to traditional gate valves.
Beyond mining, the DRC is investing heavily in urban water supply through organizations like REGIDESO. Cities like Kinshasa, Lubumbashi, and Goma are expanding their water treatment plants and distribution networks. Butterfly valves play a pivotal role here, managing the flow of potable water and wastewater. The demand for resilient seated butterfly valves and flanged concentric butterfly valves is at an all-time high as the nation strives to meet UN Sustainable Development Goals for clean water and sanitation.
Established in 2003, Tianjin Tanggu Water-Seal Valve Co., Ltd. (TWS Valve) is a professional manufacturer that integrates design, development, production, installation, sales, and service. With two state-of-the-art plants in Tianjin, China, we have emerged as a leading global supplier of water management valve products and solutions. Our brand "TWS" is synonymous with quality and innovation in the international valve market.
Over 20 years of manufacturing excellence.
Strong "TWS" brand presence worldwide.

The global shift toward "Industry 4.0" is reaching the DRC. We are seeing an increasing trend toward automated flow control. Mining and power companies are moving away from manual operation to electric and pneumatic actuators. TWS Valve is at the forefront of this trend, producing Gearboxes with IP67 ratings and integrated electrical actuators to ensure optimal matching and remote monitoring capabilities.
TWS Valve’s core products include a comprehensive series of resilient seated butterfly valves (wafer, lug, U-section, flanged concentric, flanged eccentric, and grooved end types). We also offer flanged rubber seated gate valves, swing check valves, dual plate check valves, and Y strainers. Our commitment to "All For Customers, All From Innovation" ensures that we provide the most cost-effective and reliable solutions for the unique challenges of the Congolese market.
