Northern Valves provides Tangshan Sanyou Chemical Co., Ltd. with a full range of fluid control solutions, including gate valves, globe valves, and check valves, for its core production units in the soda ash, viscose staple fiber, and caustic soda processes. Addressing critical operating conditions in Sanyou Chemical's ammonia-soda process soda ash production, such as concentrated seawater transport, high-temperature steam circulation, and transport of highly corrosive media, Northern Valves' products, with their superior sealing performance and corrosion resistance, ensure the stable operation of the production system.

Gate valves are used in the main process pipelines and storage tank inlet/outlet systems, offering low flow resistance and reducing transport energy consumption when fully open. Globe valves precisely control steam and material flow rates, adapting to process adjustment needs. Check valves effectively prevent backflow of media at pump outlets and within pipelines, avoiding production fluctuations and equipment damage.

For a long time, Northern Valves' products, with their high reliability and low maintenance costs, have helped Sanyou Chemical achieve stable production and reduced consumption, supporting the efficient operation of its "two alkalis and one chemical" circular economy model, becoming a benchmark example of valve application in the chemical industry.
