Denmark, a nation globally recognized for its pioneering efforts in green energy and sustainable water management, represents one of the most sophisticated markets for industrial valve technology. As a leading Bs5163 Gate Valve Factory & Supplier in Denmark, we recognize that the Danish industrial sector demands more than just hardware; it requires precision engineering that aligns with the country's strict environmental and efficiency standards.
The Danish water sector is characterized by a high degree of decentralization and a strong focus on "Water-Wise" cities. Copenhagen and Aarhus are leading the way in integrating smart water technologies to reduce non-revenue water (NRW) to record lows. In this context, the BS5163 gate valve—known for its resilient seating and robust design—becomes a critical component. Whether it is for the vast district heating networks that heat over 60% of Danish households or the advanced wastewater treatment plants like those managed by BIOFOS, the reliability of flow control is paramount.
Danish engineers prioritize longevity and low maintenance. Our BS5163 valves are designed to exceed these expectations with high-grade ductile iron and corrosion-resistant coatings.
With Denmark's focus on zero-leakage systems, our resilient seated gate valves provide a 100% bubble-tight seal, essential for modern Danish water grids.
As Denmark moves toward Industry 4.0, our valves are increasingly paired with IP67-rated actuators for remote monitoring and automated control.
Tianjin Tanggu Water-Seal Valve Co., Ltd (TWS Valve) found in 2003, and is a professional manufacturer which integrates design, development, production, installation, sales and service. We have 2 plants, one in Xiaozhan Town, Jinnan, Tianjin, and the other in Gegu Town, Jinnan, Tianjin. Now we have become one of China’s leading suppliers of water management valve products and product solutions. Furthermore, we have built up our own strong brands “TWS”.
TWS Valve’s quality system is strictly certified by ISO 9001, and most products have approval of CE, WRAS. Our core products include all series Resilient seated butterfly valve which are wafer /lug/U section/flanged concentric /flanged eccentric/grooved end type, Flanged rubber seated gate valve, Flanged swing type check valve, Dual plate check valve, Y strainer, and more.
We continue to develop and diversify products by water management requirements, including Balancing valves, Air releasing valves, and Backflow preventers. We also design and produce Gearboxes with IP67 grade and Electrical actuators to guarantee an optimal matching with our valves.






Our role as a Bs5163 Gate Valve Factory & Supplier in Denmark extends across various specialized sectors. The Danish climate and industrial rigor require valves that can withstand both coastal salinity and intense municipal pressure.
Denmark is a world leader in district heating. Our BS5163 gate valves are utilized in isolation points within the massive underground network of pipes that transport hot water from CHP (Combined Heat and Power) plants to residential units. The resilient seat ensures that even after years of dormancy, the valve can be closed securely for maintenance without leakage.
With major players like Ørsted and Vestas headquartered in Denmark, the offshore wind sector is booming. Our valves, particularly those with specialized seawater desalination coatings, are used in the cooling systems of offshore substations and coastal power facilities, where corrosion resistance is the highest priority.
The Danish food industry (including dairy giants like Arla) requires valves that meet strict hygiene and reliability standards. Our WRAS-approved valves ensure that water used in processing remains uncontaminated, supporting Denmark's reputation for high-quality food exports.
The BS5163 standard has long been the benchmark for gate valves in waterworks. However, the industry is evolving. Today, a "standard" valve is no longer enough for the Danish market. We are seeing a significant shift towards Intelligent Flow Control.
Modern Danish water utilities are looking for valves equipped with sensors that can detect vibration, pressure changes, and seat wear. As a forward-thinking supplier, TWS Valve is integrating AI-ready features into our production line. By combining our high-quality ductile iron castings with IP67-grade worm gears and electrical actuators, we provide a hardware foundation that is ready for the digital twin systems used by Danish engineers to model city-wide water flows.
TWS Valve products are widely used in water treatment, distribution, wastewater, dams, and hydropower plants worldwide.
Our management theory remains: "All For Customers, All From Innovation". As the quality is high, the price competitive, and the service professional, our products have been exported to Europe, North America, Southeast Asia, and Africa. We are dedicated to defining new standards in valves for water. FLOW CONTROLLED BY TWS—join us on our voyage to a more efficient future.
From the bustling industrial hubs of Jutland to the municipal infrastructure of the Capital Region, TWS Valve provides the reliability, innovation, and technical support that Danish industry demands. As your Bs5163 Gate Valve Factory & Supplier in Denmark, we are committed to excellence in every cast and every seal.
