Industrial Applications
Our duckbill check valves and rubber expansion joints serve critical roles across diverse industrial sectors, delivering reliable fluid control and piping solutions for complex engineering challenges worldwide.
Wastewater & Stormwater Management
Duckbill valves prevent backflow in sewage outfalls, storm drains, and treatment plants. Rubber expansion joints accommodate thermal movement and vibration in large-diameter piping systems, ensuring long-term reliability in harsh wastewater environments.
Marine & Coastal Protection
Essential for ship ballast systems, bilge pumps, and coastal outfalls. Our corrosion-resistant materials withstand saltwater exposure while providing reliable one-way flow control. Expansion joints handle ship movement and thermal cycling in marine piping systems.
Thermal Power Plants
Critical components in cooling tower systems, condenser water circuits, and ash handling systems. Our products handle high-temperature conditions and provide vibration isolation in power generation facilities, ensuring continuous operation and system integrity.
HVAC & Building Systems
Rubber expansion joints compensate for thermal expansion in chilled water systems, heating circuits, and air handling units. Duckbill valves prevent backflow in drainage systems and provide overflow protection in commercial and industrial buildings.
Flood Control & Tidal Systems
Flap gate valves and duckbill valves provide automatic flood protection by allowing drainage while preventing tidal or flood water intrusion. Essential for coastal infrastructure, urban drainage, and emergency flood management systems worldwide.
Chemical & Industrial Processes
Specialized rubber compounds resist aggressive chemicals while maintaining flexibility. Applications include process water systems, chemical transfer lines, and industrial waste management. Custom flanging accommodates various international standards and specifications.
