The VU Series Hydraulic Check Valve is a unidirectional flow control valve designed to ensure fluid flow in one direction while preventing backflow. Commonly referred to as a non-return valve, it can be installed in either vertical or horizontal pipelines. The valve is constructed from high-quality materials such as steel or stainless steel, chosen based on the specific requirements and working conditions of the industrial application. Available in various sizes ranging from DN8 to DN50 (1/4 Inches to 2 Inches, the standard working pressure for sizes 1/4 Inches to 1 Inches is 420 bars, while for sizes 1-1/4 Inches to 2 Inches, the pressure rating is reduced to 315 bars to accommodate larger valve dimensions.
