INTRODUCTION
Leader Horizontal Lift Check valves are designed with high sensitivity to pressure so that the valve closes immediately before significant fluid starts flowing backward. Fluid reversing backward causes damage to equipment like boilers or pumps. The valve is activated by the flowing material in the pipeline. The pressure of the fluid passing through the system opens the valve disc, while any reversal of flow will lose the valve disc. Closure is accomplished by the weight of the check mechanism, by back pressure. Disc guides enhance the proper alignment of the disc and seat configuration when the disc closes. Entirely automatic in action, depending upon differential pressure and velocity of flow within the line to perform their functions of opening and closing.
