체크 밸브
This check valve adopts swing, lift and wafer structure, with a simple and compact design, mainly used to automatically prevent medium backflow in pipeline systems. Made of ductile iron, cast steel and stainless steel, it is suitable for conveying media such as water, oil, gas, sewage and mild corrosive fluids. It works automatically relying on medium pressure without external operation, effectively maintaining one-way flow and protecting pumps and other equipment. Applicable to medium and low-pressure working conditions in petroleum, chemical, water treatment, HVAC and urban water supply and drainage, it features stable opening and closing, good sealing performance, low flow resistance and easy installation. Strictly tested for pressure and sealing, it runs reliably with long service life, providing safe and effective anti-backflow protection for various industrial pipeline systems.
