Product Overview
The Wafer Type Lift Check Valve is designed to prevent backflow in liquid and gas pipelines, offering compact structure, reliable sealing, and low flow resistance.
Using a vertical lift disc design, the valve opens automatically under forward flow and closes quickly when reverse flow occurs, effectively protecting pumps, pipelines, and system equipment.
The wafer body allows easy installation between flanges, saving space and weight compared to traditional flanged check valves.
