The United Arab Emirates is located at a crucial geographical position connecting Asia, Europe, and Africa, and it is an extremely important maritime transportation hub. Its ship transportation industry is highly developed, so it has strict requirements for the performance and reliability of marine valves. During the process of a certain large-scale ship manufacturing and renovation project, there was an urgent need to find a valve that could adapt to the complex marine environment and meet the diverse needs of the ship's efficient operation. At that time, the C95800 TRIPLE ECCENTRIC LUG BUTTERFLY VALVE under J-VALVES stood out with its outstanding comprehensive performance and won the bid successfully in the project tender.
Material Advantage
The C95800 is made of aluminum bronze alloy. The surrounding sea areas of the United Arab Emirates have a relatively high seawater salinity and extremely strong corrosiveness. Valves made of ordinary materials are prone to corrosion perforation, which will then lead to a decline in their performance. However, the aluminum bronze alloy of C95800 exhibits extremely excellent seawater corrosion resistance. In the marine environment with high salinity and strong corrosion, it can ensure the integrity of the valve structure and the stability of its functions for a long time, greatly extend the service life of the valve, and effectively reduce the maintenance and replacement costs derived from corrosion problems, possessing remarkable practical value.
Structural Advantage
Triple Eccentric Structure: The C95800 TRIPLE ECCENTRIC LUG BUTTERFLY VALVE adopts a unique triple eccentric design. When the valve is closed, the sealing surface of the sealing pair will gradually change from line contact to three-dimensional spatial conical surface sealing. Relying on this structural characteristic, even under complex working conditions such as high pressure and high temperature, the valve can still achieve zero-leakage sealing, effectively prevent the leakage of media such as fuel and seawater, build a solid safeguard for the safety of ship navigation, and fully meet the strict requirements of the ship's pipeline system for sealing.
Lug Design: As we all know, the internal space of ships is relatively cramped, and the space available for installation and maintenance operations is quite limited. The lug design adopted by the C95800 triple eccentric lug butterfly valve plays an important role. In the installation process, this design can not only make the installation process more convenient and efficient, without the need to adopt the flange clamp method additionally, thus reducing the occupation of installation space and lowering costs; in the later maintenance stage, this design also facilitates the staff to quickly carry out the disassembly and replacement of valve components, helps to improve the maintenance efficiency, shorten the ship's downtime for maintenance and repair, and ensure that the ship's operation efficiency remains at a stable level.
The project construction team strictly follows the layout of the ship's pipeline system and the relevant requirements for valve installation to carry out the installation work of the C95800 TRIPLE ECCENTRIC LUG BUTTERFLY VALVE in an orderly manner. In the early stage of construction, it is necessary to accurately measure and mark the installation positions of the pipelines, and comprehensively clean up the impurities, oil stains, etc. at the pipeline interfaces to ensure that the installation surfaces are clean and flat.
During the installation process, make full use of the characteristics of the lug design, place the valve stably at the pipeline interface, then pass the bolts through the installation holes reserved in the lugs, accurately align the flange holes of the pipelines, and gradually and evenly tighten the bolts to ensure a tight connection between the valve and the pipeline and good coaxiality, avoiding adverse effects on the sealing performance and the subsequent operation of the valve due to installation deviations.
Throughout the entire installation process, always strictly follow the specifications and process requirements for ship valve installation, conduct real-time monitoring on various installation parameters of each valve, such as bolt pre-tightening force, valve levelness and perpendicularity, and make timely adjustments according to the actual situation, aiming to ensure that the valve installation quality meets the qualified standards. At the same time, properly complete the installation record work to retain accurate data for subsequent commissioning and operation and maintenance work.
In this project, the C95800 TRIPLE ECCENTRIC LUG BUTTERFLY VALVE has been widely used in key pipeline systems such as the ship's seawater cooling system, fuel delivery system, and ballast water system. Since it was put into use, the valve has always maintained a stable and reliable operation state, and no failure situations caused by problems such as corrosion and leakage have occurred. In terms of the seawater cooling system, it effectively guarantees the cooling effect of the ship's engine and other related equipment; in the fuel delivery system, it can ensure the accurate delivery of fuel and successfully avoid the safety hazards and economic losses brought about by fuel leakage; in the ballast water system, it realizes the rapid switching and precise flow control of ballast water, thereby improving the ship's handling performance.
The person in charge of the project pointed out that the performance of the C95800 TRIPLE ECCENTRIC LUG BUTTERFLY VALVE of J-VALVES Company in actual application far exceeded expectations. It has excellent corrosion resistance, sealing performance, and convenient installation and maintenance characteristics, which not only effectively reduce the ship's operation and maintenance costs but also significantly improve the overall safety and reliability of the ship. J-VALVES has been focusing on industrial valve solution fields since 2018. The successful application of the C95800 triple eccentric lug butterfly valve in the ship project in the United Arab Emirates further demonstrates its professional strength in the field of marine valves and also lays a solid foundation for more cooperation in the future.
