Carbon Steel Swing Check Valve, API 6D, WCB, 2 IN, CL600, RF

Product Name: Carbon Steel Swing Check Valve
Design Standard: API 6D
Body Material: ASTM A216 WCB
Size: 2 Inch, DN50
Pressure: Class 600 LB, PN100
End Connection: RF Flanged

Universal Cast Steel Check Valves are engineered and manufactured to meet international standards such as API 6D, BS 1868, ASME B16.34, or equivalent. Designed to minimize flow resistance and pressure drop, these valves are ideally suited for horizontal pipeline installations. The seat ring is lapped and screwed, ensuring a tight shutoff and long-lasting service.
The valve's disc is meticulously designed, machined, and guided for efficient automatic shutoff even under zero pressure conditions. Featuring a compact structure and low-emission design, these valves are perfect for environments requiring high performance and minimal leakage. In standard configuration, swing check valves are equipped with a bolted cover and a free-swinging clapper, which responds to flow conditions and ensures reliable closure.
While these swing check valves are best suited for horizontal pipelines, heavier disc weights may cause chattering issues. In such cases, dampers or counterweights can be added to address this concern.

Product Features

» Backflow Prevention: The cast steel swing check valve is designed to prevent backflow in the pipeline. Flow moves through the valve in a straight line, minimizing pressure drop. The disc swings open as the media flows, and back pressure holds it in the closed position when the flow reverses.
» Flexible Installation: These valves are suitable for both horizontal and vertical installations, provided they are installed correctly according to the flow direction indicated on the body of the valve.
» Tailored Accessories: A range of optional accessories, including bypasses, locking devices, counterweights, and more, are available to cater to specific customer needs and operational requirements.
