Precision Flow Control and Pipeline Protection. The efficiency of any fluid system relies entirely on the quality of its valves. Atradesen provides an elite selection of UPVC and PVC industrial valves, including True Union Ball Valves, Check Valves, and Y-Strainers, engineered for leak-proof isolation and precise throttling. Built to handle working pressures up to 1.6 MPa (PN16), our flow control components feature robust EPDM/FPM seals and easy-maintenance designs, making them the ultimate choice for municipal water treatment, commercial aquaculture, and high-pressure chemical dosing systems.
