  • Special site
  • Official site

A coupling that allows for high flow of fluid without worrying about pressure loss with a ball valve!

In addition to the conventional 24mm diameter, the 2-inch connector TDU 50 mm has finally arrived! This meets the increasing demand for modularity in data center architecture. 【Full Flow】 The ball valve is arranged to ensure a linear flow path, providing excellent flow efficiency and pressure loss. 【Easy Operation, Safe Connection】 - No special procedures are required for operation; simply turn the lever for easy operation. - It is not affected by residual pressure in the fluid, allowing for connection even under pressure. - The valve can only be opened when connected, and it remains closed when separated. 【Swivel Mechanism】 Prevents hose twisting, allowing for smooth operation.
