In industrial pipeline systems, check valves are essential components used to prevent backflow of media. Among them, the lug type check valve is favored in many applications due to its unique structure and installation method.     Structural Features The lug type check valve is a one-way valve with threaded lug connections. It typically consists of a valve body, valve disc, valve seat, and a spring (in some models). The most notable feature of this valve is the presence of multiple threaded lug holes on both sides of the valve body, allowing it to be directly bolted to the pipeline flanges without the need for additional nuts. Common materials used include carbon steel, stainless steel, and ductile iron, which are selected based on the specific operational requirements. Compared to the wafer check valve, the lug type check valve offers a more secure installation, capable of withstanding higher pipeline loads. It also supports single-end maintenance, making it suitable for applications that require frequent disassembly and maintenance.   Working Principle: Unidirectional Flow, Preventing Backflow The core function of the lug type check valve is to ensure that the fluid flows in only one direction. In the event of backflow, the valve disc quickly closes to prevent damage to equipment caused by the reverse flow of the medium.   (1) During normal flow: The fluid pressure pushes the valve disc open, allowing the medium to flow smoothly through the pipeline.   (2) When the flow decreases or backflow occurs: The valve disc automatically closes under the action of the spring or gravity, preventing the backflow of the medium and protecting the pipeline and equipment from damage. Some lug type check valves are equipped with a spring-assisted closing mechanism, which responds more quickly to fluid changes, reduces water hammer effects, and enhances system safety.   Main Application Scenarios Due to its unique structure and stable performance, the lug type check valve is widely used across various industries:   (1) Water Treatment and Supply Systems It ensures one-way water flow, preventing backflow when pumps stop, and protects the system from damage.   (2) Oil and Gas Pipelines Suitable for high-pressure and high-temperature conditions, it prevents backflow of fluids from impacting equipment.   (3) Chemical Industry In pipelines conveying corrosive media, lug type check valves made from corrosion-resistant materials ensure production safety.   (4) Power Plants and Boiler Systems Used in steam delivery pipelines to prevent pressure fluctuations from affecting equipment.   (5) Industrial Fluid Control Ideal for systems transporting various liquids, gases, or low-viscosity fluids, improving system stability.   Advantage (1) Stable Installation The threaded lug design allows the valve to be installed or removed independently without affecting the entire pipeline system, making maintenance easier. &nbs...

Recently, DERVOS successfully completed a local project in Singapore, providing high-quality globe valve products that ensured efficient operation and safety throughout the project. Background The client for this project was a Singapore-based on-site repair and maintenance company, primarily responsible for the daily maintenance and emergency repairs of industrial facilities. Their core requirement was to provide reliable isolation valves for high-pressure steam systems, ensuring efficient and safe operation under high-pressure and high-temperature conditions. Facing issues such as valve aging and high maintenance costs, the customer urgently needed a solution that could provide long-term stable performance. Product Features To meet the customer's strict requirements for steam medium management, we provided a high-pressure steam isolation globe valve. This valve is specifically designed for steam isolation, featuring excellent high-pressure resistance. It is manufactured using precision machining processes to ensure stable sealing and long-lasting performance, even under high-temperature and high-pressure conditions. The valve not only meets strict international standards but also underwent multiple tests at the project site, demonstrating exceptional performance. Project Results The globe valve was successfully installed and put into operation. The client reported that their high-pressure steam system is running smoothly, with more stable and safer operation. The precise control of the valve not only improved the efficiency of maintenance work but also significantly reduced system failures and safety risks. The client highly praised the performance and service of our products, stating that our solution greatly supported their daily maintenance and emergency response capabilities. The success of this project has not only enhanced the client's maintenance efficiency and system safety but also laid a solid foundation for future cooperation between both parties. We are proud to have been involved in this project and look forward to continuing to provide high-quality fluid control solutions for our clients in the future.

On the evening of June 27, 2024, DERVOS joyously celebrated its 16th anniversary. We not only invited esteemed partners to join us in the celebration, but also meticulously planned a unique journey through time. With the theme "Golden Years, Timeless Classics," we took a nostalgic trip back to the 1990s in Hong Kong. The celebration was filled with a sense of nostalgia and joy, with every detail seemingly transporting us through time to experience the unique charm of that golden era. To match the theme, all partners and colleagues carefully prepared Hong Kong-style outfits, with many colleagues even mimicking classic looks. We specially arranged a fashion show for the occasion. Everyone confidently walked the catwalk, showcasing their Hong Kong-style elegance. Under the flash, everyone exuded a unique charm, as if time had turned back, and the glamour and charm of the 1990s were once again brought to life. In order to let our partners to experience the essence of traditional Chinese culture, we meticulously prepared a "lacquer fan" making activity. By dripping different pigments into the water, the fans spun in the water, creating unique and beautiful patterns that left everyone in awe. Each lacquer fan became a one-of-a-kind piece of art, embodying the creativity and ingenuity of our clients. Our dear partners wrote blessings for Dervos on folding fans and stamped their own exclusive seal, leaving behind cherished memories. The versatile Dervoser added endless joy to the celebration. Sheila and Noisy's jazz dance performance brought the atmosphere to a climax. As the dynamic music played, their passionate performance energized everyone. With the explosive background music, everyone took to the dance floor together, dancing and celebrating this unforgettable moment. That night, we not only reminisced about the glorious past but also looked forward to future prospects. Dervos will continue to uphold the spirit of "Timeless Classics, Everlasting Brilliance," and together with every customer and colleague, write even more magnificent chapters. We thank everyone who has supported and accompanied Dervos, and we look forward to continuing our journey together, creating a better tomorrow.
