Carbon Steel (CS) CHECK VALVE

The L&T Carbon Steel Check Valve is exceptionally sturdy, rugged and durable, with a reputation for quality, integrity and long service. They are designed for tight sealing and ease of operation. The valves are available with flanged ends as well as butt-welded ends, in pressure ratings from ASME Class 150 to Class 1500, and in a variety of materials of construction. The flanged valves are drilled as per ASME B16.5. L&T Check Valves are of swing-type and bolted-cover construction. They conform to BS 1868 and also meet the general requirements of API 600, including shell wall thickness.   The check valve body provides a full port without pockets from inlet to the valve seat. On the downstream side, the body has generous proportions to facilitate full swing of the disc to reduce disc erosion and flow resistance. L&T gate valves and check valves feature a seal-welded seat ring that offers a leak-proof design as it eliminates the leakage path between the seat ring and the body.
