About the product
Ball check valve with flange from Fucoli-Somepal, designed to prevent backflow in pressurised systems such as pumping and pressure-boosting pipelines. The function relies on a free-moving ball that seals against the seat on reverse flow, giving a simple design with few moving parts. The valve is made of ductile iron with a ball in aluminium or ductile iron, and the body is protected with epoxy coating of at least 250 µm thickness. The valve is available in sizes DN40 to DN350, where the larger sizes are supplied for PN10 and the smaller ones for PN10/16. Installation is between flanges according to EN 1092-2 with face-to-face length according to EN 558. The ball can be ordered with alternative weights to adjust the opening characteristics, and the valve can be supplied with a lightweight design.
