Check Valves

Check valves, or non-return valves, are essential components designed to allow media to flow in one direction while preventing backflow. When media flows in the correct direction, it opens the valve by moving the disc away from the seat. Conversely, backflow forces the disc back, sealing the valve. Swing check valves are ideal for high-flow scenarios, handling viscous materials and fluids with suspended solids. Ball check valves offer a compact solution for high-pressure systems and viscous media. Piston check valves are best for low-flow and low-viscosity applications. Poppet check valves are tailored for low-pressure environments, including hydraulic systems. Diaphragm check valves utilize flexible diaphragms to block reverse flow. Food grade and sanitary air blow check valves are crucial for clearing residual media from pipelines, ensuring hygiene and preventing corrosion. Foot valves are installed at pump suction lines to avert back-siphonage.
