British Standard Swing Check Valve SWD-M12
The Swing Check Valveis also called a check valve or a check valve, and its function is to prevent the medium in the pipeline from flowing backward. The valve of the opening and closing member is opened or closed by the flow of the medium and the force to prevent the backflow of the medium from being called a check valve.
The valve plate of the swing check valve is in the shape of a disk and rotates around the shaft of the valve seat passage. Because the flow through the valve is streamlined, the flow resistance is smaller than that of the lift check valve. It is suitable for large diameter pipes with low flow rate and flow compensation variation. It is not suitable for pulsating flow, and the sealing performance cannot be improved.
This type of valve should generally be installed horizontally in the pipeline.
The Swing Check Valve is suitable for nominal pressure PN1.0MPa~42.0MPa, Class150-2500; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540°C for various pipelines used to prevent The media is reversed.
By using different materials (WCB, CF8(M), CF3(M), 1Gr5Mo, 15CrMo1V, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium, and urea. Oil, chemical, pharmaceutical, fertilizer, electricity, and other pipelines.
