ASTM A217 C12 Swing Check Valve, API 6D, 18 Inch, CL600, RF

Product Name: ASTM A217 C12 Swing Check Valve, Bolted Cover
Design Standard: API 6D
Body Material: ASTM A217 C12
Size: 18 Inch, DN450
Pressure: Class 600 LB, PN100
End Connection: RF

Universal Cast Steel Check Valves are engineered and manufactured to meet international standards, including API 6D, BS 1868, ASME B16.34, or equivalent. These valves are designed to minimize flow resistance and pressure drop, ensuring efficient performance. They are suitable for horizontal installation only. The lapped and screwed seat ring guarantees a tight shutoff and extended service life.
The valve's disc is precisely designed, machined, and guided, enabling efficient automatic shutoff even at zero pressure. With a compact structure and low emission service, this check valve provides reliable operation. In its standard configuration, the swing check valve features a bolted cover and a free-swinging clapper, which serves as the closing member, responding to the flow conditions.
Swing check valves are optimal for horizontal pipeline installations. However, heavier disc weights may lead to chattering, in which case, dampers or counterweights should be incorporated to maintain smooth operation.

Product Features

» Cast steel swing check valve prevents backflow in the line, with flow directed straight through the valve for minimal pressure drop. The disc swings open as media flows through the line, while back pressure holds the disc in the closed position.
» Versatile installation: The valve can be installed in horizontal or vertical lines, but must be oriented according to the media flow direction indicated by the flow direction arrow on the body.
» Customizable accessories: A range of accessories, including bypasses, locking devices, counterweights, and more, are available to meet specific customer requirements.
