The main function of the bottom valve is to prevent medium backflow, prevent the pump and its drive motor from reversing, and to discharge the medium in the container. Check valves can also be used on pipelines that supply auxiliary systems where the pressure may exceed the main system pressure.Depending on the material, check valves can be used on pipelines for various media.When installed on a pipeline, the check valve becomes one of the fluid components of the complete pipeline, and the opening and closing process of its valve disc is influenced by the transient flow state of the system it is in; conversely, the closing characteristics of the valve disc also react to the fluid flow state.

H42X bottom valve is a one-way opening and closing valve that prevents medium flow. It is generally installed at the bottom end of the underwater suction pipe of a water pump to prevent the liquid in the pump pipe from returning to the water source. It functions to allow inflow only and not outflow. The valve cover has multiple water inlets and reinforcing ribs, making it less prone to clogging. It is mainly used in water suction pipelines, waterways, and for support. The calibers include single disc, double disc, and multi-disc types; connection methods include flange connection and threaded connection.

H42X Bottom Valve Structure and Principle: H42X bottom valve consists of components such as the valve body, valve disc, valve cover, bushing, and sealing ring. Water from the source enters the valve body through the valve cover; under the pressure of the fluid, the valve disc opens to allow water flow. When the pump stops, the pressure in the outlet pipe quickly closes the valve disc, preventing the liquid from flowing back to the source, thus ensuring smooth water pumping and saving water energy loss.
