RTV Ruitong valve casting BS1868 Swing Check valve is used to prevent back flow in the line .Flow is in a straight line through the valve resulting in minimal pressure drop . The disc swings into the open position as the media flows through the line .Back pressure in the line holds the disc in the closed position . RTV Ruitong valve Casting Swing Check Valves may be installed in horizontal or vertical lines ,but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body .
RTV Ruitong valve casting API6D Swing Check valve is used to prevent back flow in the line .Flow is in a straight line through the valve resulting in minimal pressure drop . The disc swings into the open position as the media flows through the line .Back pressure in the line holds the disc in the closed position . RTV Ruitong valve Casting Swing Check Valves may be installed in horizontal or vertical lines ,but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body .
The design and manufacturing of the product comply with the requirements of the American National Standard ANSIB16.34 and the American Petroleum Institute Standard API16D.
The valve body and valve cover are connected by bolts, with a rating greater than 63K under high pressure. The middle flange adopts an internal pressure self sealing structure, making the product lightweight and reliable in sealing.
