It is possible to flow a certain amount of fluid in a stepwise manner! There are many proven results in filling equipment and more!

We would like to introduce a two-stage opening and closing ball valve equipped with a two-stage rotary air-operated drive unit handled by Nippon Diavalve Co., Ltd. By installing a sub-cylinder in our standard rotary air-operated drive unit (90-degree rotation, Scotch yoke type, W piston), the valve can mechanically perform a two-step operation during opening and closing. This allows for a controlled flow of a certain amount of fluid in a staged manner, and it has a proven track record for capacity control in quantitative shipping lines and water hammer prevention. 【Features】 ■ Installation of a sub-cylinder in our standard rotary air-operated drive unit ■ Mechanically capable of two-step operation during valve opening and closing ■ Allows for a controlled flow of a certain amount of fluid in a staged manner ■ Proven track record for capacity control in quantitative shipping lines and water hammer prevention *For more details, please refer to the catalog or feel free to contact us.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
