In this video, we demonstrate the installation and operation of the 3/4 inch wafer check valve in chemical processing applications. You'll see how this lift-type H71H valve prevents backflow in pipeline systems, with detailed explanations of its carbon steel construction, wafer connection design, and real-world performance benefits. Follow along as we showcase its compact installation, energy-saving features, and suitability for handling water, oil, gas, and air in demanding industrial environments.
