Description
L&T’s FS Lift Check Valve, Class 800, Screwed/Socket Weld, 13Cr Steel + Hard-Faced Trim (IBR) is supplied in 15 mm to 50 mm at Class 800. Check valves stop reverse flow without any external operation — line pressure alone opens and closes them. On a pump discharge they prevent backspin and the water hammer that follows an abrupt stop. Certified to IBR, with the Form III-C documentation that a boiler inspector will expect to see. Forged A105 gives a dense, void-free body — why forged construction is specified for small-bore high-pressure duty. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
