Our Past Projects
Product Name
Duvalco Butterfly Valves
Year
2024

In year 2024, Duvalco supplied DN800 and DN1800 butterfly valves for a PUB project showcasing Duvalco’s capability in handling large-diameter, high-performance flow control systems. This project follows the success of 2023 where Duvalco supplied DN2000 butterfly valves for another PUB project, marking consecutive projects of large diameter butterfly valves. This back-to-back success not only highlights Duvalco’s engineering depth and manufacturing capacity, but also PUB’s trust in their products for Singapore’s evolving water infrastructure.

Product Name
Kubota Ductile Iron Pipe
Year
2024-2025

In year 2024, Duvalco supplied more than 10KM of Kubota Ductile Iron Pipes size ranging from DN100 to DN350 across Changi Airport. The use of Hazard Resilient Ductile Iron Pipes (HRDIP) at critical taxiway locations is especially noteworthy as these HRDIP pipes are engineered to withstand extreme ground movement. The characteristic feature of hazard resilient ductile iron pipes is that even if a ground displacement occurs, the joints between the different pipes expand and contract and deflect at the joints and the joints do not fall apart even if a strong force is applied, like on a chain. This kind of installation not only enhances operational safety but also ensures long-term resilience against natural hazards, making it a smart investment for aviation infrastructure.

Product Name
EJ Manhole Covers and Gratings
Year
2024

In year 2024, Duvalco supplied 300M of gratings and manhole covers at Chagi Airport. EJ is the world leader in the design, manufacture and distribution of access solutions for water, sewer, drainage, telecommunications and utility networks worldwide. EJ products are engineered to handle extreme wheel loads (up to Class F900), making them ideal for runways, taxiways, and refueling zones.

Year
