2205 duplex steel high-pressure check valve, model H44W, H44Y, swing type, flange connection, pressure PN16-PN100, diameter DN15-DN600. 2205 duplex steel has two structures: ferritic and austenitic. It has excellent resistance to pitting and crevice corrosion and is commonly used in media such as seawater, acids, and wastewater containing chloride ions.
The 2205 duplex steel high-pressure check valve is designed to prevent the backflow of liquid in pipelines. It features a hard metal seal and is widely used in engineering projects across industries such as water treatment, chemical engineering, petroleum, papermaking, textile printing and dyeing, electronics, power plants, and seawater desalination. The valve body and other parts are made of precision cast blanks and need to go through processes such as solution treatment, passivation and acid washing, fine processing, shot blasting, grinding and deburring. The finished products must undergo shell strength tests and sealing tests. Only after passing the tests will they be packed and dispatched.
The function of the 2205 duplex steel high-pressure check valve is to prevent backflow, allowing the medium to flow only in one direction and blocking the reverse flow. The fluid pressure flowing from the inlet direction pushes the valve core (valve plate) away from the valve seat. At this time, the valve is opened and the medium passes through the valve. When the pressure of the medium at the inlet end decreases and is less than the sum of the self-weight of the valve plate and the reverse pressure of the medium, the valve plate is pushed towards the valve seat and tightly presses against it. At this time, the valve is closed and the medium cannot flow.
