Key Characteristics of Vertical Lift Check Valve
Installation Requirements: It must be installed vertically (with the pipeline axis vertical), and the fluid must flow "from bottom to top". This is because the reset of the "lifting valve core" depends entirely on gravity; vertical installation ensures the valve core descends properly and achieves reliable sealing. Horizontal installation may cause the valve core to tilt, leading to leakage.Applicable Scenarios: Typically used in vertical pipelines, such as water pump outlets (to prevent water backflow when the pump stops), high-rise water supply risers, and boiler water supply pipelines.
Key Characteristics of Horizontal Swing Check Valve
Installation Requirements: It must be installed horizontally (with the pipeline axis horizontal), as the closure of its "swing valve disc" relies on "gravity + reverse fluid pressure". Only horizontal installation allows the valve disc to rotate and reset freely; vertical installation may cause jamming or sealing failure.Applicable Scenarios: Commonly used in horizontally arranged pipelines, such as water supply pipelines, air conditioning water circulation pipelines, and low-pressure oil circuits, to prevent damage to equipment (e.g., water pumps) caused by reverse fluid flow.
